Disclosed is an electrolysis process which is characterized by carrying out the electrolysis of an aqueous alkali metal halide solution while supplying a cathode liquor into a cathode compartment formed between a cation exchange membrane positioned substantially horizontal and a cathode plate of gas-liquid impermeability, with which the membrane is wetted, then a mixed stream of the cathode liquor and cathode gas being removed from the cathode compartment. Also disclosed is an electrolytic cell which is comprised of an upper anode compartment and a lower cathode compartment partitioned by a cation exchange membrane positioned substantially horizontal, said anode compartment having therein substantially horizontal anodes and an anolyte solution inlet and outlet, and said cathode compartment having a cathode plate with gas-liquid impermeability and a cathode liquor inlet and an outlet of a mixed stream of the cathode liquor and cathode gas.
