    摘要： A cathode catalyst for a fuel cell includes an Ru—Se alloy having an average particle size of less than or equal to 6 nm. The Ru—Se alloy is amorphous catalyst. A membrane electrode assembly and a fuel cell system include the cathode catalyst. A catalyst for a fuel cell is prepared by drying a ruthenium solution including a water-soluble ruthenium precursor to obtain a first dried product; subjecting the first dried product to a first heat-treatment to obtain a heat-treated product; adding an Se solution including a water-soluble Se precursor to the heat-treated product to obtain a mixture; drying the mixture to obtain a second dried product including ruthenium and Se; and subjecting the second dried product to second heat-treatment.

    摘要： A stack for a direct oxidation fuel cell and a direct oxidation fuel cell system including the stack are provided. The stack for a direct oxidation fuel cell includes at least one membrane-electrode assembly including an anode and a cathode facing each other and a polymer electrolyte membrane interposed between the anode and cathode, and separators disposed at both sides of the membrane-electrode assembly. The cathode includes a platinum-based catalyst and a selective catalyst that can be active for reduction of an oxidant. The stack for a direct oxidation fuel cell of the present invention can have improved performance by including the platinum-based catalyst and the selective catalyst in a cathode catalyst layer, thereby minimizing catalyst poisoning due to a crossed-over fuel and maximizing catalyst activity for reduction of an oxidant.
