ABSTRACT:
A cathode catalyst for a fuel cell including a metal selected from the group consisting of In, Ga, and combinations thereof, and Ru—Ch supported on the metal, where Ch includes a material selected from the group consisting of S, Se, Te, and combinations thereof. In one embodiment, the Ru—Ch includes from about 70 to about 95 atom % of Ru, and from about 5 to about 30 atom % of Ch, and/or the Ru—Ch is supported in an amount from about 5 to about 80 wt % based on the Ru—Ch and the metal.
