▎ 摘　　要

NOVELTY - The method involves mixing the metal precursor solution and the polymer compound that forms a filament to obtain a mixed system A. The mixed system A is mixed with the carbon carrier for partially winding the polymer compound on the surface of the carbon carrier, to obtain a solid-liquid mixed system B. The solid-liquid mixed system B is evaporated under reduced pressure to obtain a viscous slurry C. The viscous slurry C is dried to obtain a carbon carrier D loaded with a metal precursor. The carbon carrier D is placed in a reducing atmosphere for reduction treatment and/or heat treatment in an inert atmosphere to obtain a carbon-supported metal catalyst. USE - Method for preparing carbon-supported metal catalyst for fuel cell (all claimed) used as energy conversion device in automobile. ADVANTAGE - The polymer compound is used to wrap the surface of the carbon carrier to improve the wettability of the carbon carrier, so that the metal precursor salt is evenly adsorbed and precipitated on the surface of the carbon carrier, thus increasing the metal loading and improving the stability of the metal in the carbon carrier. The carbon-supported metal catalyst has a high metal loading, and the metal is evenly loaded on the surface of the carbon support, which improves the catalytic performance and stability of the carbon-supported metal catalyst. The carbon-supported metal catalyst has high stability and improves the utilization rate of the metal catalyst, thus improving the catalytic performance and stability of the fuel cell and reducing the material cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a carbon supported metal catalyst. DESCRIPTION OF DRAWING(S) - The drawing shows a half-wave potential comparison diagram of the oxygen reduction linear scan curve of the metal catalysts. (Drawing includes non-English language text)
