Abstract
An electrolytic cell comprising a plurality of anodes and cathodes and a separator positioned between each anode and adjacent cathode to form a plurality of anode compartments and cathode compartments, in which a barrier member is positioned at an upper part of the cell between an anode and an adjacent separator, or between a cathode and an adjacent separator, and which, in operation shields the separator from contact with a gaseous product of electrolysis which may collect in an upper part of the anode compartment, or in an upper part of the cathode compartment. The separator may be an ion-exchange membrane, and the barrier member protects the separator from chemical attach by gaseous products of electrolysis.
