  2. WHAT are fuel cells? • Energy devices that continuously transform chemical energy to electrical energy. • Fuel often used is Hydrogen • Very efficient with environment friendly by-products.

  3. 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

  4. THERMO relevance • ∆(Free Energy)=∆(enthalpy)-(T)∆(entropy) • Thermodynamics is sweet!!

  5. “Real World Usage”

  6. Conclusion • Get to know fuel cells!!! • They are the FUTURE!!
