  11. 12. What is a Fuel Cell Vehicle?
  12. 13. FUEL CELL VEHICLES-2004 FORD The Ford Focus FCV fuel cell system is efficient, quiet, and produces zero emissions. Ford has announced plans to have a three year demonstration program of 5-10 fleet vehicles in Vancouver, Canada in 2004.
  13. 14. FUEL CELL VEHICLES-2003 Honda Honda is delivering a family of new FCX fuel-cell vehicles to its first customer, the city of Los Angeles. Honda plans to lease approximately 30 fuel-cell cars in California and Japan during the next several years. The fuel-cell itself is propelled by electricity generated by a hydrogen-oxygen chemical reaction—and its only emission, remarkably, is water vapor.
  14. 15. FUEL CELL VEHICLES-2003 TOYOTA Its only exhaust is water vapor. Its secret? A hydrogen fuel cell that harnesses the electricity of separated atoms and molecules as they strive to be electrically balanced. Developed entirely in-house, FCHV-4 shows Toyota on the leading edge of fuel-cell technology. (NOT AVAILABLE)
  15. 16. FUEL CELL VEHICLES-NISSAN X-TRAIL FCV Nissan is actively developing fuel cell vehicles (FCVs) that have low environmental impact and save energy. Commercialization is scheduled for 2003.(?????)
  16. 17. FUEL CELL VEHICLES-GM The Hy-wire has no internal combustion engine, instrument panel, brake or accelerator pedals – but it does have ample power supplied by a GM fuel cell that runs on hydrogen. PROTOTYPE

  22. 23. SOME SURPRISING FACTS ABOUT HYDROGEN A) HYDROGEN STORES & TRANSPORTS ENERGY. A CARRIER NOT A SOURCE. A) BATTERIES Where does hydrogen come from? Fossil : nat gas, propane, gasoline, methanol Renewable : electric wind, solar, etc. electrolyze water Methane (CH4), methanol(CH3OH), ammonia(NH3?) Q1) IS HYDROGEN A revolutionary NEW ENERGY SOURCE? Q2) WHICH IS MORE EFFICIENT, FUEL CELL OR BATTERIES?
  23. 24. INTERNAL COMBUSTION ENGINE oil (gasoline) -> IC engine 15% H2 Fuel Cell Efficiency BATTERY POWERED ELECTRIC VEHICLE Oil-> power plant -> electricity ~=45% transmission~=80% battery charging ~=80% electric drive system ~=80% .45 x .8 x .8 x .8 = 23% FUEL CELL POWERED ELECTRIC VEHICLE Oil-> power plant-> electricity~=45% electricity transmission ~=80% H2 electrolyzer max efficiency ~=70% H2 fuel cell max efficiency ~=50% Electric drive system ~=80% .45 x .8 x .7 x .5 x .8 = 10%
