Title:
ACTIVE MATERIAL FOR FUEL CELL ANODES INCORPORATING AN ADDITIVE FOR PRECHARGING/ACTIVATION THEREOF
Document Type and Number:
WIPO Patent Application WO2003038926
Kind Code:
A3
Abstract:
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.
