Disclosed herein are a gas diffusion layer, a preparation method therefor, and a membrane electrode. The gas diffusion layer comprises a substrate, and a microporous layer attached to at least a portion of a surface of the substrate. Raw materials of the microporous layer comprise a phosphorus-containing compound solution; the mass concentration of the phosphorus-containing compound solution is 45% to 47%, and the mass of the phosphorus-containing compound solution is 2% to 5% of the total mass of the raw materials of the microporous layer. In the present application, the phosphorus-containing compound is placed in the gas diffusion layer. Due to the porous structure and good gas permeability of the gas diffusion layer, the phosphorus-containing compound can be fully diffused therein, increasing the opportunities for contact with free radicals, thereby effectively reducing the attack of free radicals on a proton exchange membrane, further protecting the chemical structure of the membrane, and alleviating the speed of decrease of proton conductivity to a certain extent. Therefore, with regard to a membrane electrode containing the described gas diffusion layer, both the durability and the electrical performance of the membrane electrode are considered.
