ABSTRACT:
A foraminous protective cathode for diaphragm-type electrolytic cells having a steel cathode and polymeric microporous separator reduces or eliminates separator plugging thereby increasing useful life-expectancy of the separator. The protective cathode positioned between the primary steel cathode and separator has an electroconductive metallic surface of nickel, cobalt, copper, chromium, noble metals, noble metal oxides or mixtures thereof.
