摘要:
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.
