Abstract

The current invention is to provide an oxygen gas diffusion cathode for brine electrolysis which reduces an initial electrolysis voltage and is excellent in the durability against short-circuit, and an electrolytic cell and an electrolytic method using the same. The oxygen gas diffusion cathode for brine electrolysis includes a gas diffusion layerand a reaction layeron one surface of an electro-conductive substrate, and an electro-conductive layeron the opposite surface thereof. The present oxygen gas diffusion cathode reduces the resistance of the electro-conductive substrateand supplies uniform current by mounting the electro-conductive layer
