To provide a diffusion electrode for fuel cell in which water is hard to accumulate and gas flows smoothly.
An aqueous dispersion containing water-repellent resin particles is added to a mixture produced by diffusing carbon fibers sufficiently to an organic solvent, and then it is stirred at a low stirring speed thus obtaining slurry. The slurry is applied onto a carbon paper and calcined thus producing a diffusion electrode for fuel cell consisting of a ground layer and a diffusion layer. According to this method, a diffusion electrode for fuel cell in which water-repellent resin particles are not aggregate but dispersed in the ground layer can be obtained. As a result, a diffusion electrode for fuel cell in which water is hard to accumulate and gas flows smoothly is provided.
