Abstract
High fuel efficiency and clean exhaust gas are the two most important requirements in hydrazine‐air fuel cells. Four anodes of sintered nickel plaque were studied for these purposes, each one containing either cobalt, nickel, palladium, silver, or platinum as a catalyst. Exhaust gases were determined with a gas chromatograph, the consumption of hydrazine in the anolyte was analyzed chemically, and fuel efficiencies and unreacted product gases were evaluated based on these data. Consequently with the silver catalyzed electrode, 97% fuel efficiency was attained at 50 mA/cm2 at 25°C.
