Catalytic layer structure of fuel cell

The utility model discloses a catalyst layer structure of a fuel cell, which comprises an anion exchange membrane, an anode gas diffusion layer and an anode catalyst layer positioned between the anion exchange membrane and the anode gas diffusion layer, and the anode catalyst layer comprises a first catalyst layer and a second catalyst layer, the activity of the first catalyst layer is different from that of the second catalyst layer, the first catalyst layer is located on one side of the anion exchange membrane, and the second catalyst layer is located on one side of the anode gas diffusion layer; the catalyst layer is of a two-layer structure and comprises the first catalyst layer and the second catalyst layer which are different in activity, and due to the fact that the two catalyst layers are different in activity, the reaction rates of the catalyst layers and hydroxyl ions are different, the distribution state of generated water in the anode and the water discharging structure are changed, and water disc
