Abstract: Disclosed is a stack pack type electrolytic cell for the generation of chlorates or hypochlorites of sodium or potassium having the ability to make economical use of materials while eliminating the necessity for large external studs for the electrode components, housings to retain fluids and intercell piping connections since the cell can be increased in capacity by adding chambers and electrode stack packs to the cell makeup or adding electrodes to the stack packs. Such an electrolyzer can utilize mass produced components to produce various capacities and can be assembled either monopolar or bipolar in configuration to make most efficient use of existing electrical supply equipment.

Abstract: Electrolytic cell in which hollow cylindrical electrodes are arranged concentrically, anode within the cathode, and having a tubular ion permeable membrane supported on the outside of the anode separating the anolyte and the catholyte. The anolyte is contained within the membrane-anode structure, affording reduced construction cost and greater efficiency per unit of cell volume.
