429 42, 429 44, 429 27, 4292182, 429105

A hydrogen storage alloy active material for the anode of Ovonic instant startup/regenerative fuel cells. The active material includes a hydrogen storage alloy material with a water reactive chemical hydride additive, which, upon utilization of the active material in an anode of an alkaline electrolyte fuel cell, gives the anode added benefits, not attainable by using hydrogen storage alloy material alone. These added benefits include 1) precharge of the hydrogen storage material with hydrogen; 2) higher porosity/increased surface area/reduced electrode polarization at high currents; 3) simplified, faster activation of the hydrogen storage alloy; and 4) optionally, enhanced corrosion protection for the hydrogen storage alloy.

429 40, 429 27, 429 42, 429 44, 429 17

Fuel cell oxygen electrode and instant startup fuel cells employing such oxygen electrode. The oxygen electrode operates through the mechanism of redox couples which uniquely provide multiple degrees of freedom in selecting the operating voltages available for such fuel cells. Such oxygen electrodes provide the fuel cells in which they are used a âbufferâ or âchargeâ of oxidizer available within the oxygen electrode at all times.
