Abstract:
The cathode catalyst for a fuel cell of the present invention includes M-Co-Ch where M is at least one metal selected from the group consisting of Ru, Rh, Pd, Os, Ir, Pt, and combinations thereof, and Ch is at least one element selected from the group consisting of S, Se, Te, and combinations thereof. The cathode catalyst of the present invention has high activity and excellent selectivity for reduction of an oxidant, and is capable of improving performance of a membrane-electrode assembly for a fuel cell, a fuel cell system including the same, and a membrane-electrode assembly including the same.
