Harnessing Hydrogen for Power:
Hydrogen Cars

What exactly is a Hydrogen Car
In a hydrogen car, its primary source of power is from breaking down hydrogen The use of hydrogen usually happens by two methods
Hydrogen can be burned much like the combustion reaction that takes place in the gas powered cars seen today. This is called a internal hydrogen combustion engine
Hydrogen can be set up to react with oxygen to produce water and electricity. This is called a fuel cell.
Ways of Getting Hydrogen These are the important ways now used :
S.S
BMW’s project for hydrogen car
BMW took the initiative step to create a hydrogen fuel car
IT tested it’s BMW7 first time at aug 7 2015
it accelerated 0-60 in 9.5 sec only
Hydrogen fuel cell:-
It gets hydrogen from hydrogen tank and air from atmosphere.
it generates power by using these two gases
The power can be depends upon no. of individual fuel cells used(0.7v)
Hydrogen tank:-
It is present at the back portion of the car.
It as made up of impact resistant polymer
Power control unit:- It governs the flow of power
Comparable Efficiencies Hydrogen Fuel cells at over 50%
efficiencyFossil fuel powered car at 10% - 20%
efficiencyHybrid powered cars have 30% - 35%
efficiencyEthanol is less efficient than fossil fuel
- ethanol gets 20% less mpg than fossil fuels
AdvantagesZero emissions (pure water is produced)No dependence on foreign oilAbility to harvest solar and renewable
energyNot many moving parts in a vehicle (more
mileage before things start breaking) Hydrogen weighs less than gasoline
(vehicles would not need as much energy to move)
Companies Getting Involved
Ford- P2000
Honda- FCX
BMW - Hydrogen 7
Mazda- Wankel motor
General Motors- Sequel
conclusion
If use this technology we can completely reduce the wastage of fossil fuels. We can also reduce the cost of fuel
