Bipolar electrodes and electrolytic cell therewith

In a bipolar electrode for a diaphragm type electrolyser, a self-supporting, upstanding bipolar electrode structure comprising, in assembled relationship, a generally vertical supporting wall, a plurality of generally vertical, laterally spaced, parallel anode plates, transversally connected to said wall, on one side thereof and extending away therefrom, and a plurality of generally vertical, spaced parallel foraminous cathode fingers, transversally connected to the opposite side of said wall and extending away therefrom, and alternating with the anodes, the improvement which comprises at least a portion of said supporting wall comprising a plurality of apertured generally vertical elongated metallic members supporting the cathode fingers and each extending between two anode plates, said cathode fingers being in communication with one another through apertures provided through said metallic members, and said portion of said wall comprising extensions of the anode plates, alternating with and clamped between the vertical elongated metallic members supporting the cathode fingers to make said portion of said wall continuous and self-supporting on the anode side thereof.
