摘要： Disclosed in the present application are a double-layer electrode for hydrogen production through water electrolysis, a preparation method therefor and an application thereof. The double-layer electrode for hydrogen production through water electrolysis comprises a current collector. The surface of the current collector is provided with at least one hydrogen/oxygen generation porous catalyst layer. The hydrogen/oxygen generation porous catalyst layer comprises a conductive porous carrier and hydrogen/oxygen generation catalyst particles dispersed on the surface of the carrier. At least one gas impurity removal porous catalyst layer is provided on the surface of the outermost hydrogen/oxygen generation porous catalyst layer, and the gas impurity removal porous catalyst layer comprises a conductive porous carrier and gas impurity removal catalyst particles dispersed on the surface of the carrier. The double-layer electrode for hydrogen production through water electrolysis has the functions of electro-catalysis, gas diffusion and gas purification, the space of the electrolytic cell can be saved, the energy consumption is reduced, and the equipment stability under fluctuation power input is improved.
