ABSTRACT OF THE DISCLOSURE An electrolytic process is disclosed for electrolysis of an aqueous alkali metal chloride solution using a cation exchange membrane as a separator in an electrolytic cell, which process comprises effecting the electrolysis utilizing the impact resilience of springs positioned at the anodes and exerting positive pressure on the cathode compartments of the cell. Not only is stable operation at low cell voltage for a prolonged period of time possible, but also the production of high purity alkali metal hydroxide containing a reduced amount of sodium chloride.
