Abstract: In a bipolar electrode electrolysis apparatus, particularly for the electrolysis of saline solutions, an enclosure is formed of electrically insulating material and has monopolar terminal electrodes for connection to current leads. The enclosure has therein a plurality of compartments having open sides through one wall of the enclosure. A plurality of bipolar electrodes are mountable in each compartment. The bipolar electrodes are mounted by supporting structure in each respective compartment so that the bipolar electrodes may be removed from and inserted into a respective compartment through the open side thereof.

Abstract: An electrolysis device includes at least two layers of electrodes, each electrode layer including a plurality of bipolar electrodes, each bipolar electrode including a cathode portion and an anode portion. The electrode layers are spaced from each other in parallel planes, and the bipolar electrodes of each electrode layer are arranged in a checkerboard fashion, such that each cathode portion in each electrode layer is spaced from and faces an anode portion in an adjacent cathode layer, thus forming a plurality of electrolytic cells between the electrolytic layers.
