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.
