Abstract
An ion exchange membrane electrolyzer having at least one electrolytic cell containing a gas diffusion cathode, a current distributor, an anode supported by a wall of the electrolytic cell housing, and spacing means separating the current distributor which is in contact with said gas diffusion cathode from said ion exchange membrane wherein the force exerted by gas pressure applied to one face of the gas diffusion cathode is transmitted to said anode via said current distributor, and/or said spacing means, and said ion exchange membrane.
Claims8
A membrane electrolyzer having at least one electrolytic cell having elements comprising:
- (A) a cell housing divided into two compartments, an anode compartment containing an anode and anolyte and a cathode compartment containing a cathode and catholyte, said compartments separated by an ion exchange membrane,
- (B) a gas diffusion polymer cathode having current distributing means,
- (C) an internally supported anode or said anode supported by an endplate of said anode compartment, and
- (D) spacing means in said cathode compartment adjacent to said ion exchange membrane, wherein the force exerted by gas pressure applied to said gas diffusion cathode is transmitted to said anode by cell elements comprising said spacing means and said ion exchange membrane.
