摘要

The present invention relates to a cathode catalyst for a direct oxidation fuel cell, a method for manufacturing the same, a membrane-electrode assembly for a direct oxidation fuel cell and a direct oxidation fuel cell system including the same, wherein the cathode catalyst is used for a carbon-based material and a carbon-based material. 1 selected from the group consisting of supported Pt _x S _100-x , Pt _x Se _100-x , Pt _x Te _100-x , Rh _x S _100-x , Rh _x Se _100-x and Rh _x Te _100-x And a cathode catalyst for a direct oxidation fuel cell comprising at least one compound.;The cathode catalyst for the direct oxidation type fuel cell of the present invention is excellent in activity and selectivity for the reduction reaction of the oxidant, and can improve the performance of the fuel cell membrane-electrode assembly and the fuel cell system including the same. In addition, the method for producing a cathode catalyst for a direct oxidation fuel cell of the present invention can reduce the particle size of the active material supported on carbon, thereby improving the activity of the catalyst.;Fuel cell, electrode, catalyst, active, selectivity, deactivated
