| abstract |
The present invention relates to a cathode catalyst for a fuel cell, and a membrane-electrode assembly for a fuel cell and a fuel cell system comprising the same. The cathode catalyst for a fuel cell includes A-B-S, where A is selected from the group consisting of Ru, Rh, and combinations thereof, the B is selected from the group consisting of W, Mo, and combinations thereof, and the A-B-S is shaped as a nanowire. Since the cathode catalyst for a fuel cell of the present invention has excellent activity and selectivity for reduction of an oxidant, it can improve performance of a membrane-electrode assembly and a fuel cell system including the same. |
