Abstract
A carbonaceous electrode for use in a bipolar electrolytic cell is treated on one side with a source of aluminum to form an adherent layer of aluminum carbide thereon. The electrode is arranged in the cell such that on the passage of electrolyzing current the treated surface functions as a cathode. On electrolyzing the cell, chlorine is produced on each anode surface and aluminum is produced on each cathode surface.
