Abstract
Provided are a cathode catalyst layer and a preparation method and use thereof, and a fuel cell. The method includes: mixing a catalyst, water, and an alcohol with a pore-forming agent to obtain a mixture; dispersing the mixture into a Nafion solution to obtain a slurry; and coating the slurry onto a surface of a diffusion layer to obtain a coated diffusion layer, and subjecting the coated diffusion layer to calcination and freeze-drying in sequence to obtain the cathode catalyst layer.
