CATHODE CATALYST FOR FUEL CELL, THE METHOD OF PREPARING SAME, MEMBRANE-ELECTRODE ASSEMBLY FOR FUEL CELL COMPRISING SAME AND FUEL CELL SYSTEM COMPRISING SAME

摘要

A cathode catalyst for a fuel cell, a method for manufacturing the same, a membrane-electrode assembly for the fuel cell comprising the same, and a fuel cell system are provided to improve the performances of the membrane-electrode assembly and the fuel cell system. A cathode catalyst comprises a carbon-based material and Ru-In-Ch supported on the carbon-based material, wherein Ch is a material selected from a group consisting of S, Se, and Te. A membrane-electrode assembly(131) for a fuel cell comprises an anode(3) and a cathode(5) positioned to face each other, and a polymer electrolytic membrane(1) positioned between the anode and the cathode. The cathode includes the cathode catalyst.
