▎ 摘  要

NOVELTY - The method involves using multiple mixtures to coat and modify the carbon-supported platinum-based catalyst, and calcining in a specific reducing atmosphere to obtain a catalyst that is co-coated with oxides and carbon materials with good durability. The problems of decreased conductivity and decreased activity of the catalyst caused by the coating of simple oxides are solved by co-coating of oxides and carbon materials, so that the catalyst obtains good durability while hardly changing the activity. USE - Method for preparing fuel cell catalyst with high durability. ADVANTAGE - The catalyst modification and coating method has simple steps, solves the problem of reduced conductivity and activity of the catalyst caused by simple oxide modification, and the obtained membrane electrode does not decrease in activity, and has good durability. The method is of great significance for improving the life of the fuel cell, promoting the development of fuel cell technology, and planning commercial applications. The treatment process is easy to realize large-scale production, which is of great significance for solving the current problem of insufficient durability of fuel cells. The bonding force between the coating layer and the catalyst is improved, the calcination process can improve the lattice structure of the Pt nanoparticles and effectively improve the durability of the catalyst.
