1.4.3 HovaPOR CG7200

Description:

Hovacal is a portable calibration gas generator for accurate gas- vapor mixtures with selectable humidity and

temperatures up to 200 C.

HOVACAL is based on the principle of dynamic evaporation of liquids and mixture with carrier gas. The calibration gas

generator consists of a supply unit and an evaporator. The supply unit containing the pump for liquid, flow controller for

carrier gas and temperature controller for the evaporator. The evaporator is installed separately from the supply unit.

Both are connected via a link for carrier gas, liquid and power supply. The gas output of the evaporator can be fed in a

heated line or directly in the gas analyzer. Accuracy, reproducibility and stability of the calibration gas mixture are

achieved with a precision mass flow controller for carrier gas and a peristaltic pump for liquid. The liquid flow can be

verified with help of a balance, the carrier gas flow with a gas meter. This guarantees the verification with primary

standards at any time.

The complete calibration gas generator is mounted in a portable case. The calibration of emission monitoring systems

needs span gas with hydrogen chloride, ammonia, hydrogen fluoride and mercury chloride. Cheap standard solutions in

a wide concentration range are available for these components. The reagents have nearly infinite stability over time. No

gas cylinders are necessary. Precise water vapor mixtures for calibration of moisture analyzers or for gas humidifying

can be produced with water and air or with another carrier gas. Vapor gas mixtures with organic components can be

generated with organic reagents. Span gas for multi component analysis can be easily achieved with mixed reagents.

The elevated temperature of the gas vapor mixture avoids adsorption and corrosion of gas exposed surfaces.

Safety Benefits:

low pressure of the generated span gas no leakage problems: only the required amount of gas is

fewer high-pressure cylinders lessen the safety risk produced

simple transport without safety precautions simple disposal e.g. by means of neutralization

simple storage of the standard solutions in plastic bottles

Technical Benefits:

high accuracy: due to precise mass flow meter and balance controlled liquid metering

can be verified with primary methods: by means of gas meter and balance

quick gas response time: due to minimized adsorption effects

moisture content up to 60 Vol.-%: due to liquid evaporation of up to 6 ml/min

wide range of output: concentration range of 1:100 with one standard solution

gas flow up to 1000 l/h as standard (higher gas flows as options)

independent of temperature since evaporates completely

gas temperatures up to 200 C: adjustable depending on the application

quick change of components by replacing the standard solution

gas mixtures produced from combined standard solutions

customer-defined components can be generated by the user

1.5.1 - 1.5.4 Current Density - and Temperature Distribution

Measurement

1.5.1 Current Scan High Res

Description:

In a fuel cell the locale conditions differ which leads to an

inhomogeneous mass conversion resulting in an inhomogeneous

current production. One of the keys to a deeper understanding of PEM

fuel cells, including the DMFC, is the measurement of the current

density distribution.

The devices of the series "current scan highres" are characterized by

a high resolution. The shown device has a resolution of 32 x 36 points

with an area of 50 x 50 mm. The data shows an inhomogeneous

current distribution which is caused by a depletion of hydrogen near

the outlet.

Assembly:

The devices of this series use a segmented electrode with segments

of about 1mm conducted to single electronic loads trough a

multilayered printed circuit board. The electronic loads are realized

with amplifiers who work as current source or sink. So the device can

be used on the anode or optionally on the cathode side. The principle

is shown in the following picture.

The membrane with the catalytic layers and the gasdiffusion layers will

be placed directly on the multilayerd printed circuit board. The size of

the device is limited, because the complexity grows quadratically with

the size or resolution. For large fuel cells there is another principle

available which is realized in the devices of the series "current scan

lin".

Features:

high resolution (electrodes of about 1mm)

20 mA per segment (more on request)

temperature range up to 120 C (200 C on request)

standard sizes are available (special designs on request)

Usage:

measurement of the current density distribution of a fully operating fuel cell

usable as anode or cathode of a single cell

detailed analysis of flow fields, manifolds, flow distribution and materials like gas diffusion layers

data mining for the simulation and optimization of fuel cells

fault diagnostic in fuel cells

1.5.2 Current Scan Lin

Current Density - and Temperature Distribution Measurement

Description:

In a fuel cell the locale conditions differ which leads to an

inhomogeneous mass conversion resulting in an inhomogeneous

current production. One of the keys to a deeper understanding of

PEM fuel cells, including the DMFC, is the measurement of the

current density distribution. Important is this in large fuel cells for a

save and reliable operations as well as a high lifetime. Up to now a

problem was the high complexity.

The shown device of type "current scan lin" has a resolution of 14 x

14 measurement cells on an area of 100 x 100 mm and of 3 mm

thickness. It will be placed between the two halfs of a bipolar plate at

an arbitrary place in the stack or function itself as a bipolar plate. The device of this type. The measurement of the

temperature is also possible.

Assembly:

The single measurement cells are conducted in series in rows and

columns. So the complexity for the connection wires for the data

acquisition of the signals depends only linear on the size or

resolution. So it is possible to measure at arbitrary large fuel cells.

The principle is shown in the following picture for example at 3 x 3

measurement cells.

The principle is based upon that the permeability of a magnetic material

is depending on the magnetization and the temperature. The current

which has to be measured flows through the coils and causes this

magnetization. The alternating currents i

1

(t) to i

n

(t) will be feed one after

the other into the matrix to activate the rows 1 to n. At the columns the

voltages u

1

(t) to u

n

(t) will be acquired as measurement signals. The

measurement cells which are not activated by an alternating current

deliver nothing to the measurement signal. In general n measurement

points can be reached with 2n wire pairs. So the complexity for control

and evaluation electronics is linear.

Features:

resolution of about 7 x 7 mm

with offset current extendable measurement range

calibration in the inserted state possible

temperature range up to 120 C

standard sizes are available (special designs on request)

Usage:

measurement of the current density and temperature distribution in a fuel cell stack

1.5.3 Current Scan Shunt


Description:

detailed analysis of flow fields detailed analysis of materials

optimization of fuel cells fault diagnostics in fuel cells

long-term tests resolution depends on design

current range depends on design standard devices are available

special designs on request mass production possible

With the current scan shunt, the current density distribution in fuel cells can be measured. Because of the simple

internal structure it is suitable for mass production. It is easy to use and the evaluation electronics can be connect via

USB to any computer. In a fuel cell the local conditions differ, which leads to an inhomogeneous mass conversion

resulting in an inhomogeneous current production. One of the keys to a better understanding of PEM fuel cells, DMFC

and other electrochemical cells is the measurement of the current density distribution. It is important for a save and

reliable operation as well as a high lifetime.

Application

The device of type current scan shunt shown has a resolution of 10 x 10

measurement cells and an active area of 50 cm. Because of the simple

internal structure it is suitable for mass production. So the current

scan shunt can also be applied in series production of fuel cells. It can

be used for example for control applications.

The sensor plate has a thickness of 0,7 mm. Because the sensor plates

are very thin they can be laminated together with a thicker part where

arbitrary channals can be milled into the surface. So if it is wished by

the customer the senor plate can be used as a flow field and the gas

diffusion layer can be placed directly on the gold plated sensor plate.

The sensor plate can be placed at an arbitrary position in the stack. Because of the simple internal structure the sensor

plates are suitable for mass production.

Measurement Principle

The devices of current scan shunt series use a low ohmic shunt

resistor for current measurement. We produce two different designs.

The first one is made out of material with a very low temperature

coefficient. In this case the measurement is temperature independend

and no further calibration is necessary. This is an efficient and easy way

for measurement. The second design is made from a special copper

layer. Because of the high temperature coefficient of copper a

temperature compensation is necessary

during the measurement. The current scan

shunt is produced in licence of the DLR

(German Aerospace Center). For both

design the signals from the shunt resistors

are connected to a multiplexer which automatically switches the signals to an amplifier and

evaluation electronic with Analog-to-Digital converter. The resolution is limited, because of

the complexity. The complexity grows quadratically with the number of rows and colums of

measurement cells. For each measurement cell two wires are necessary, therefore for an

array with n x n measurement cells 2n

2

wires are necessary.

So the current scan shunt is the best choice if there is enough space for the wires,

especially for small fuel cell or when a low resolution is sufficient. For large fuel cells we

recommend the current scan lin device of our successful current scan product line, which

works in a different way and has a linear complexity.

1.6.1 V Scan

Description:

special designs on request

With the V scan, the single cell voltage in fuel cell stacks can be measured. Because of a special design a large number

of cells, resulting in a high voltage, is no problem. The V scan has a galvanic insulated fiber optic interface for save and

reliable operation. To prevent male functions a technique for detecting open circuits is included.

In a fuel cell stack the local conditions differ, which leads to an unequal distribution of the cell voltages. To prevent

damages of the fuel cell stack the voltage of each cell has to be kept above a specific level. So the single cell voltage

measurement is essential for a reliable and save operation of a fuel cell stack.

The devices of the series V scan provide single cell voltage measurements in fuel cell stacks up to 600 V. To minimize

the effort it is directly supplied from the fuel cell stack. So no extra power supply is necessary.

The base of the V scan is a printed circuit board which contains all the necessary semiconductors. It is brought with

contact springs in direct contact to the fuel cell stack. So no wires to or from the fuel cell stack are necessary. This

reduces the amount of wiring work to zero which is essential for a save and reliable operation of a single cell voltage

measurement device.

A wide choice of contact pins is available. Also a wide range in the distance between the contacts is possible.

The V scan starts operation from an average cell voltage of 0,3 V.

0 V or a reverse voltage of single cells can be detected as long as the average single cell voltage of the stack is above

0,3 V.

For a save and reliable operation it is equipped with a fiber optic interface. So it is completely galvanic insulated. To

prevent male functions a technique for detecting open circuits is included. With a special algorithm it is possible to

detect and show the position of open connections.

Measurement Principle

Of course single semiconductors can not handle a very high voltage. So the V scan is divided internally into groups. The

measurement data have to be transferred from group to group until the

fiber optic interface is reached or commands have to be transferred from

the fiber optic to each group. The groups are all on a different potential, so

the data lines can not be connected together.

A galvanic insulation with optocouplers would be a way to overcome this.

But it would result in a complex and bulky design. So the groups are

connected with current sources.

A logic 0 is transferred with a low current and a logic 1 is transferred with a

high current. An open connection to the fuel cell stack would result in

wrong measurements and so may lead to wrong control operations or even

an emergency shut down. To solve this problem the V scan provides a

method to detect open connections.

The measured voltage for both cells would be nearly zero because the open

input is discharged by the input resistor Rin of the analog to digital converter.

Application

The device of type V scan is designed for a fuel cell stack with 240

cells. The open circuit voltage will be approximately 240 V.

Custom made devices

The V scan is manufactured on customer requirements. Various contacts are possible, from simple spring contacts to

spring loaded contact probes with various head forms for graphite bipolar plates as well as stainless steal bipolar

plates. Also the distance between the contacts can be varied in a wide range. The length is adapted to the special stack.

If the device is ordered longer, respectively with the capability to measure more cells, than necessary the contacts

beyond the last cell in the stack must be short circuited. But this capability is limited! For the last group a higher

average cell voltage would be necessary to power the device. For best performance the amount of contact pins,

respectively measurement canals of the V scan should be designed especially for the amount of cells in the fuel cell

stack. For experimental setups several shorter devices of type V scan which may overlap can be used.

With a special command very small current sources are

connected to the inputs of the analog to digital converter.

If this is done the measured voltage for cell 2 will be zero

and the measured voltage for cell 3 will be the sum of

both cell voltages. For a good connection this small

currents will have no effect. So an open circuit can be

detected.

- Customer benefits

low channel costs compared to solutions with conventional A/D cards and external signal conditioning (no

assembly and wiring effort)

fast and effective start-up

Concept description:

The MCM concept unites all kinds of different types of channel under a single communication and data processing

interface. Apart from measurement inputs and signal outputs, this also includes power drivers, load and switching

modules.

In addition to the excellent electrical properties of the individual channels, the integrated signal conditioning, time-

synchronous operation of all IOs and an extremely compact design were important design criteria.

Due to the modular system, the number of channels and channel type are highly scalable. MCM units can there-fore be

precisely matched to individual

applications. Thanks to

decentralised data prepro-

cessing, no powerful and

there-fore, no expensive

control unit is required. This

makes MCM interesting for

applications with a small

number of channels too.

In addition, trigger

mechanisms on the hardware

side in conjunction with the

generation of timestamps

enable synchronous operation

of several MCM units. Even

applications with several

hundred channels are no

problem.

1.6.4 MCM-U08All voltage measurement

Description:

The MCM-U08AII has an individual ADC, including associated voltage reference, available per channel. The supply and

data transmission of the channel is carried out via a separate insulated path.

This design guarantees completely time-synchronised acquisition and complete galvanic decoupling of all channels. In

addition, it permits maximum flexibility in the use of the measurement channels and effectively prevents mutual

interference. Each channel also possesses an individual measurement range switching circuit, automatic contact

interruption detection and a protection circuit that effectively intercepts dangerous voltage peaks.

1.7.1 - 1.7.5 Gas Monitoring

1.7.1 AP29 - Sampling Probe

Description:

AP29 is an accessory to Hydrogen leak Detector

H2000 PLUS, which allows you to do automatic leak

testing. Controlled by the H2000 PLUS, it draws a

well-defined sample of air and passes it over the

built-in hydrogen sensor. It also handles automatic

calibration of your leak test system.

The sampling probe has an automatic purging

function which can be activated before and after

sampling, and when the gas concentration exceeds a

set limit. It can therefore encounter gross leaks and

still be cleared within seconds. Together with the

unique properties of hydrogen gas this feature gives

an unprecedented reliability of your system. AP29 is

built for heavy-duty applications.

Its rugged design and serviceability makes it ideal for use in tough industrial environments. The sensor element can

be replaced without opening the probe, and the sniffer flow is drawn by a venturi pump, in order to keep pump

maintenance at a minimum. The unit can be ordered with two different sniffer flows, 1 cc/s or 3 cc/s.

AP29 keeps track of the sniffer flow and sends an alarm to the H2000 PLUS if the sniffer flow begins to drop. AP29 is

fully controlled by an APC software driver, which you easily install in your H2000 PLUS leak detector. The sampling

parameters are then set from the dispay of the H2000 PLUS. The sampling probe is fully compatible with Leak

Detection System ILS500 via the APC bus system.
