摘要：
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 layer 13 and a reaction layer 14 on one surface of an electro-conductive substrate 12, and an electro-conductive layer 15 on the opposite surface thereof. The present oxygen gas diffusion cathode reduces the resistance of the electro-conductive substrate 12 and supplies uniform current by mounting the electro-conductive layer 15.
