Abstract
The incorporation of tungsten-containing hydrogen spillover materials into a composite fuel cell anode can be helpful in preserving the carbon catalyst support materials in the fuel cell cathode during periods of hydrogen starvation. Preferred examples of such tungsten-containing hydrogen spillover materials are tungsten oxides and tungsten silicides. These materials, when physically mixed with catalyst-loaded carbon support particles in a composite anode, have shown the ability to promote hydrogen storage in amounts that, during a disruption of hydrogen gas flow, can postpone an anodic potential excursion into the oxygen evolution region for a period of at least several seconds.
