Abstract: Describes an electrolysis cell having metal anodes (preferably titanium) and metal cathodes connected together, back to back, by a metal to metal contact forming a bimetallic partition. The anodes and cathodes are in wave form with their active surfaces intermeshed together and the cell may be unipolar or bipolar with terminal positive and negative end unit cells and a plurality of intermediate cell units.

Abstract: Describes electrolysis diaphragm cells with substantially vertical, dimensionally stable, valve metal anodes and steel cathodes forming substantially vertical interelectrodic gaps therebetween with grooved, slotted, reticulated or rod type anodes and baffles on either the front or back, or on both the front and back, of said anodes to direct the anodic gases away from the interelectrodic gap, and slots or other openings in the anodes, adjacent said baffles, through which the anodic gases pass to the rear of the anodes, to thereby protect the diaphragms against destruction by the anodic gases produced in the interelectrodic gap.
