Method of increasing life expectancy of microporous separators.

摘要

A foraminous protective cathode interposed between having a steel cathode and polymeric microporous separator in a diaphragm-type electrolytic cell reduces or eliminates separator plugging thereby increasing the useful life- expectancy of the separator. The protective cathode has an electroconductive metallic surface of at least one of nickel, cobalt, copper, chromium, noble metals and noble metal oxides.
