  • Publication number: 20220216484
    Abstract: A fuel cell cathode catalyst layer structure for enhancing the durability of a catalyst is provided. The cathode catalyst layer structure includes a first catalyst portion, a second catalyst portion, and a third catalyst portion that are arranged in sequence from an area close to a diffusion layer to an area close to a proton exchange membrane (PEM); a pure platinum catalyst is placed inside the first catalyst portion, the second catalyst portion, and the third catalyst portion; platinum loads of the pure platinum catalysts inside the first catalyst portion, the second catalyst portion, and the third catalyst portion decrease progressively; and average particle sizes of pure platinum catalyst particles inside the first catalyst portion, the second catalyst portion, and the third catalyst portion increase progressively. The pure platinum catalyst with a large or small particle size is more resistant to corrosion, and improves the initial performance of fuel cell.
