Abstract

A diaphragm cell for use in the electrolysis of an aqueous solution of alkali metal chloride. The cell is provided with a chamber divided by a diaphragm into an anode compartment having at least one anode therein and a cathode compartment having at least one cathode therein. The cathode has a catalytic surface different from the active surface of the anode. The cathode surface is made of a material which catalyses the decomposition of hypochlorite ions.
