    • A filter press type ion exchange membrane electrolytic cell which comprises an anode compartment and a cathode compartment partitioned by a cation exchange membrane and which is useful for obtaining a halogen, hydrogen and an alkali metal hydroxide from an alkali metal halide aqueous solution, or oxygen and hydrogen from an aqueous alkaline solution. The filter press type electrolytic cell is characterized by:(a) an anode compartment frame and a cathode compartment frame, each having an opening at its center constituting the anode compartment or the cathode compartment and four holes in the vicinity of its corners constituting passages for (1) an alkali metal halide aqueous solution or an aqueous alkaline solution, (2) a depleted brine and a halogen gas, or an aqueous alkaline solution and an oxygen gas, (3) water or a dilute alkali metal hydroxide aqueous solution and (4) an alkali metal hydroxide aqueous solution and a hydrogen gas, the former two holes being in communication with the opening constituting the anode compartment, and the latter two openings being in communication with the opening constituting the cathode compartment,(b) a cation exchange membrane having four holes at positions corresponding to the four holes provided on the anode compartment frame and the cathode compartment frame, or a cation exchange membrane having no such four holes and being smaller than said compartment frame but slightly larger than said openings of the compartment frames,(c) an anode and a cathode having no four holes and being slightly larger than the openings of the anode compartment frame and the cathode compartment frame and smaller than the compartment frames,wherein a unit comprising said cathode compartment frame and said cathode disposed on each side thereof and a unit comprising said anode compartment frame and said anode disposed on each side thereof are alternately arranged via said cation exchange membrane, orwherein a unit comprising said anode and said anode compartment frame disposed on one side or each side thereof and a unit comprising said cathode and said cathode compartment frame disposed on one side or each side thereof are alternately arranged via said cation exchange membrane.
