HOW does it work?
• Hydrogen and Oxygen flow
• Use of anodes and cathodes
• Polymer electrolyte membrane
• Electrons must travel in an external circuit
• Formation of H20
THERMO relevance
• ∆(Free Energy)=∆(enthalpy)-(T)∆(entropy)
• Thermodynamics is sweet!!
“Real World Usage”
Conclusion
• Get to know fuel cells!!!
• They are the FUTURE!!
