Abstract:
A cathode catalyst of the present invention includes an A-B-Ch compound, where A is a metal selected from the group consisting of Pt, Ru, Rh, and combinations thereof, B is a metal selected from the group consisting of Bi, Pb, Tl, Sb, Sn, In, Ga, Ge, and combinations thereof, and Ch is an element selected from the group consisting of S, Se, Te, and combinations thereof. The cathode catalyst may be used in a membrane-electrode assembly and a fuel cell.
