Claim 0:
1. A gas diffusion layer for fuel cells, the gas diffusion layer comprises a gas diffusion layer substrate and a microporous layer slurry applied directly or by screen printing on the gas diffusion layer substrate, wherein an additive containing catechol or pyrocatechol compounds is added into the microporous layer slurry; wherein the gas diffusion layer substrate applied with the microporous layer slurry is calcined to decompose and release functional groups of an amino acid structure in the additive to form a microporous layer on the surface of the gas diffusion layer substrate; wherein the slurry used in the preparation process of the microporous layer of the gas diffusion layer contains a conductive material, a pore-forming agent, a hydrophobic agent, and a dispersing agent.
