| description | The invention belongs to the technical field of water electrolysis hydrogen production, and particularly relates to a powder composite type gas diffusion layer and a preparation method and application thereof.The preparation method of the powder composite type gas diffusion layer comprises the following steps that a first titanium powder layer is prepared, specifically, first titanium powder is subjected to first sintering treatment, and the first titanium powder layer is obtained; a second titanium powder layer is arranged on one face of the first titanium powder layer, third sintering treatment is conducted on the second titanium powder layer and the first titanium powder layer, so that the second titanium powder layer and the first titanium powder layer are integrated, and the powder composite gas diffusion layer is obtained, the granularity of the second titanium powder is smaller than that of the first titanium powder. According to the preparation method of the powder composite type gas diffusion layer, |
