    摘要: A sodium chloride electrolytic cell is provided, comprising a gas diffusion electrode that allows smooth supply and discharge of catholyte for electrolyzing sodium chloride and allows oxygen gas to come in good contact therewith. The sodium chloride electrolytic cell comprises an anode chamber having an anode into which an aqueous solution of sodium chloride and a cathode chamber having the foregoing gas diffusion electrode for producing an alkaline aqueous solution, the anode chamber and the cathode chamber being divided by an ion exchange membrane. The sodium chloride electrolytic cell is arranged to effect electrolysis in such a manner that there occurs no pressure differential between the catholyte chamber and the gas chamber in the gas diffusion electrode. Further, a nickel mesh substance is fitted in a concave portion having the same size as that of the gas diffusion electrode formed in the central portion of a thin nickel plate.
