Abstract: There is provided an ion exchange membrane electrolyzer, wherein at least one electrode is energized by coming into contact with plate spring bodies formed on the electrode side of an electrode holding member forming a space with an electrode chamber partition bonded to a plate-like electrode chamber partition by a strip-like bonded portion, the electrode has a connected portion extending from a plane parallel to the ion exchange membrane toward the electrode holding member side in a direction perpendicular to the electrode plane, the connected portion is provided with an engaging opening extending in a direction perpendicular to the electrode plane, and the engaging opening engages with an engaging member, permitting the electrode to move in a direction perpendicular to the electrode plane within the displacement range of the plate spring bodies.

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 in a flat sheet form is joined to a cathode chamber partition in a flat sheet form. An electrode retainer member in a sheet form is joined to at least one partition at a belt-like junction. A projecting strip 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 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.
