Abstract

1,011,076. Fuel cells. VARTA A.G. Dec. 3, 1962 [Dec. 5, 1961], No. 45667/62. Heading H1B. The performance of a fuel cell is improved by feeding a second more reactive fuel in addition to the main fuel, to the fuel electrode when the output of the cell falls below a determined level. The main fuel may be methanol dissolved in potassium hydroxide electrolyte, or ethylene glycol in potassium hydroxide electrolyte. The second fuel may be hydrazine and its derivatives, hydroxylamine and/or compounds thereof, boric hydrides, or soluble borohydrides, soluble aluminium hydrides, preferably lithium aluminium hydrides, or silanes. The supply of second fuel may be controlled by the current withdrawn from the cell or by the potential of the fuel electrode, a magnetic valve connected in the supply line between a second fuel reservoir and the fuel electrode being used in the latter case. The fuel electrode may comprise Raney nickel particles between conductive screens or sintered carbonyl nickel particles activated with sodium borohydride between conductive screens. The oxygen electrode described comprises a sintered silver body activated by potassium cyanate.
