摘要： The present invention contemplates a PEM fuel cell having electrical contact elements (including bipolar plates/septums) comprising a titanium nitride coated light weight metal (e.g., Al or Ti) core, having a passivating, protective metal layer intermediate the core and the titanium nitride. The protective layer forms a barrier to further oxidation/corrosion when exposed to the fuel cell's operating environment. Stainless steels rich in CR, Ni, and Mo are particularly effective protective interlayers.

摘要： 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.

摘要： The durability of a fuel cell having a polymer electrolyte membrane with an anode on one surface and an oxygen-reducing cathode on the other surface is improved by replacing conductive carbon matrix materials in an electrode with a matrix of electrically conductive metal compound particles. The electrode includes a catalyst supported on a nanosize metal oxides and electrically conductive nanosize matrix particles of a metal compound. One or more metal compounds such as a boride, carbide, nitride, silicide, carbonitride, oxyboride, oxycarbide, or oxynitride of a metal such as cobalt, chromium, nickel, molybdenum, neodymium niobium, tantalum, titanium, tungsten, vanadium, and zirconium is suitable. For example, the combination of platinum particles deposited on titanium dioxide support particles mixed in a conductive matrix of titanium carbide particles provides an electrode with good oxygen reduction capability and corrosion resistance in an acid environment.
