Abstract: The invention resides in an ion exchange membrane electrolytic cell comprising an anode chamber accommodating an anode and a cathode gas chamber accommodating a gas diffusion electrode which are divided by an ion exchange membrane. A metallic cushion is accommodated under compression between a back plate of the cathode gas chamber and the gas diffusion electrode, wherein the repulsive forces at respective points in a longitudinal direction of the metallic cushion are larger than the pressure difference between the anode chamber liquid pressure and the cathode gas chamber pressure, and its excessive pressure, which is equal to the repulsive forces minus the anode chamber liquid pressure plus the cathode gas chamber pressure, is not more than 10 kPa. The metallic cushion can be configured such that a repulsive force of the metallic cushion at a bottom part, of the cathode gas chamber is larger than that at a top part of the cathode gas chamber. The invention also resides in a method of the electrolysis of brine and producing caustic soda or chlorine by employing an ion exchange membrane electrolytic cell according to claim 1.

Abstract: A method of producing caustic soda or chlorine by employing an ion exchange membrane electrolytic cell. The method involves use of a cushion material 10 accommodated between a cathode gas chamber back plate 9 and a gas diffusion electrode 7 of an ion exchange membrane electrolytic cell 1 such that a repulsive force of the cushion material at the bottom part of the cathode gas chamber is larger than that at the top part. The excessive pressure applied to the ion exchange membrane is suppressed to prevent the generation of scratches or the like by decreasing the repulsive force of the cushion material toward the top in accordance with a differential pressure between an anode chamber pressure and a cathode gas chamber pressure.

Abstract: A method of electrolysis is provided in which salt concentration is reduced in a caustic soda aqueous solution produced in the two-chamber ion exchange membrane brine electrolytic cell which is divided, by means of an ion exchange membrane, into a cathode chamber equipped with a gas diffusion electrode as a cathode and an anode chamber equipped with an anode. The electrolysis is conducted while a differential pressure [a pressure obtained by subtracting an oxygen-containing gas pressure in the cathode gas chamber (measured by a manometer 18) or a gas pressure at an oxygen-containing gas inlet 14 from a liquid pressure in the anode chamber which is applied on the ion exchange membrane when the anode chamber is filled with brine (= brine height x brine density ÷ 2)] between the liquid pressure and the gas pressure in the cathode gas chamber of the two-chamber ion exchange membrane electrolytic cell 1 employing the gas diffusion electrode 7 is reduced.

Abstract: The invention provides an ion exchange membrane electrolyzer ensuring a satisfactory circulation of electrolyte, high electrolytic efficiency and great ridigity. An anode chamber partition (8) in a flat sheet form is joined to a cathode chamber partition (9) in a flat sheet form. An electrode retainer member (10) in a sheet form is joined to at least one partition at a belt-like junction (11). A projecting strip (13) with an electrode joined thereto is located between adjacent junctions. A space on an electrode surface side of the electrode retainer member defines a path through which a fluid goes up in the electrode chamber, and a space (16) that spaces away from the space defines a path through which an electrolyte separated from a gas at a top portion of the electrode goes down.
