3 TYPICAL FUEL CELLS :3 TYPICAL FUEL CELLS ☺ Phosphoric Acid
☺ Regenerative
☺ Alkaline
PHOSPHORIC ACID CELLS :PHOSPHORIC ACID CELLS Commercial availability
Using liquid phosphoric acid as the electrolyte
Generating 40% electricity
Operating at about 450°F
Using impure hydrogen as fuel
REGENERATIVE FUEL CELLS :REGENERATIVE FUEL CELLS A closed-loop form of power generation
Generating electricity, heat and water
Re-circulating back to the solar-powered electrolyte
Researched by NASA and worldwide
ALKALINE FUEL CELLS :ALKALINE FUEL CELLS Providing electricity and drinking water
Using potassium hydroxide as the electrolyte
Generating 70% electricity
Operating at 160°F
Requiring pure hydrogen and oxygen
Long used by NASA, on the Apollo spacecraft
