This invention discloses a gas-liquid dual-channel microporous layer, its preparation method, and its application, comprising the following steps: Step S1, zinc acetate is dissolved in methanol solution and dispersed to obtain solution A, 2-methylimidazole, hexadecyltrimethylammonium bromide, and sodium laurate are sequentially dissolved in methanol solution and dispersed to obtain solution B; Step S2, solution A is added to solution B, and after stirring, the solvent is removed to obtain a precipitate. The precipitate is vacuum dried to obtain a precursor p-ZIF-8, and the precursor p-ZIF-8 is subjected to high-temperature heat treatment to obtain porous carbon material p-ZIF-8-C; Step S3, the porous carbon material p-ZIF-8-C, a hydrophobic agent, and a solvent are mixed, dispersed, and prepared into a slurry. The slurry is coated onto a carbon fiber substrate in multiple applications. After coating, the solvent is removed by drying, and after calcination, a gas-liquid dual-channel microporous layer with a cracked surface is obtained. This invention improves the water management and gas transport capabilities inside the membrane electrode by precisely controlling the pore size of the carbon material and achieving adjustable microporous layer cracks, thereby enhancing the performance of the fuel cell.
