Abstract

A catalyst layer preparation method, the method comprising the following steps: providing a supporting layer, and soaking the supporting layer in methanol; dissolving dimethylimidazole and zinc nitrate in the methanol in which the supporting layer is soaked so as to obtain a prefabricated liquid, the surface of the supporting layer reacting to form a metal organic framework, such that a prefabricated layer is obtained; cleaning and drying the prefabricated layer, and then soaking same in a mixed solution, the solvent of the mixed solution being at least one of an alcohol solvent and water, and the solute thereof comprising transition metal ions and chloroplatinic acid; and drying the soaked prefabricated layer, and then performing heat treatment on same in a reducing atmosphere at a preset temperature to carbonize the metal organic framework, thereby obtaining a catalyst layer. The metal organic framework material is carbonized to form the catalyst layer, and the in-situ synthesis of the metal organic framework allows for homogeneity and may form catalyst layers having relatively high uniformity.
