Abstract
Disclosed is a bipolar, filter press type electrolytic cell comprising a plurality of unit cells which are arranged in series through a cation exchange membrane disposed between respective adjacent unit cells, each unit cell containing anode-side and cathode-side gas-liquid separation chambers respectively disposed in anode-side and cathode-side non-current-flowing spaces and extending over the entire upper-side lengths of anode and cathode compartments. This electrolytic cell can be utilized to stably perform, for a prolonged period of time, the electrolysis of an aqueous alkali metal chloride solution at low cost without causing not only a leakage of an electrolytic solution but also vibration of the cell and formation of a gas zone in the upper portion of the anode and cathode compartments even in the electrolysis conducted at a high current density and at a high alkali concentration.
