Abstract

Fuel cell alloy bipolar plates. The alloys may be used as a coating or bulk material. The alloys and metallic glasses may be particularly suitable for proton-exchange membrane fuel cells because of they may exhibit reduced weights and/or better corrosion resistance. The alloys may include any of the following AlxCuyTiz, AlxFeyNiz, AlxMnyNiz, AlxNiyTiz, CuxFeyTiz, CuxNiyTiz, AlxFeySiz, AlxMnySiz, AlxNiySiz, NixSiyTiz, and CxFeySiz. The alloys or metallic glass may be doped with various dopants to improve glass forming ability, mechanical strength, ductility, electrical or thermal conductivities, hydrophobicity, and/or corrosion resistance.
