Abstract
A bipolar type ion exchange membrane electrolytic cell has gas-liquid separating chambers which minimizes a pressure fluctuation in compartment frame units, deterioration of ion exchange membranes and a voltage variation in the compartment units. Upper portions of back plates 5, 3a are outwardly bent at a higher position than meshed electrode plates of each of anode and cathode compartment frames to form inversed U-shape portions; U-shaped channel members 10 are respectively placed in and fixed to the inversed U-shape portions so that spaces are formed, as passages 12, in association with the back plates, and areas defined by the inversed U-shape portions and the U-shaped channel members are gas-liquid separating chambers.
