摘要： A salt water electrolysis process for electrolyzing an aqueous alkali chloride solution capable of preventing the deterioration of a gas diffusion cathode is disclosed. A cation-exchange membrane having closely disposed to one surface thereof an insoluble metal anode and having closely adhered or mechanically attached to the opposite surface thereof a liquid permeable gas diffusion cathode is disposed in an electrolytic cell, and electrolysis is carried out while supplying salt water to the anode chamber and an oxygen-containing gas containing water as steam or fine water droplets to the cathode chamber, and an alkali hydroxide is obtained from the cathode chamber. The water-containing gas directly reaches the gas diffusion cathode and since the alkali hydroxide and the alkali carbonate formed at the surface of the cathode are dissolved in the water in the gas and removed from the electrolytic cell, deterioration of the gas diffusion cathode can be prevented.

摘要： An electrolytic cell for obtaining a caustic alkali by closely contacting a gas diffusion electrode comprising a gas-liquid permeable metal substrate and a gas-liquid permeable collector connected to the substrate to a cation-exchange membrane while supplying an oxygen-containing gas from the opposite side of the cation-exchange membrane. Grooves for taking out a liquid containing a caustic alkali are formed in the contact surface of the gas diffusion electrode with the cation-exchange membrane. By the formation of the grooves, clogging of the perforations of the gas diffusion electrode with the caustic alkali so formed is prevented, whereby the gas supply can be smoothly carried out and the electrolysis can be stably carried out without reducing the cell voltage.
