  "textContent": "Disclosed is a membrane electrode, fuel cell gas diffusion layer, and process for preparing the fuel cell gas diffusion layer, the process comprising: S coating microporous layer slurry on the surface of hydrophobic carbon paper; the microporous layer slurry was obtained by dispersing mixture of carbon powder, polytetrafluoroethylene dispersion solution, thickener, and solvent; S moving the hydrophobic carbon paper coated with the microporous layer slurry to a porous ceramic plate, and connecting a vacuum pump to the porous ceramic plate, vacuumed for adsorption pre-infiltration treatment, and then dried. S continuing to coat the microporous layer slurry on the hydrophobic carbon paper dried in step S, then drying, and then sintering at 250-400° C. to obtain a gas diffusion layer. The beneficial effects of this disclosure include: this disclosure improve the water vapor erosion resistance of the microporous layer and the durability of the gas diffusion layer.",
