Abstract
Abstract Disclosed is a substantially vertical bipolar electrolytic cell especially suited to the production of alkali metal hypochlorites, divided into a plurality of cell units by horizontal partitions and featuring a bipolar electrode design wherein a foraminous, U-shaped cathode portion adapted to receive a sheet-like anode and a sheet-like anode portion are joined around a horizontal partition by a conductive portion.
