ABSTRACT:
Disclosed is a method of conducting electrolysis in a bipolar electrolyzer. According to the disclosed method an electrical current is passed from anodes of a first electrolytic cell through an electrolyte to cathodes of the first electrolytic cell, evolving hydrogen at the cathodes. The electrical current then passes from the cathode of the cell through a bipolar unit to the anodes of a subsequent cell in the electrolyzer. The disclosed method is characterized in that the electrical current passes from the cathodes of the first cell through the bipolar unit to the anodes of the subsequent cell by first changing direction and passing laterally through a cathodic element of the backplate to conductor means between the cells, thereafter changing direction and passing through the conductor means, and then changing direction and passing laterally through the anodic element of the backplate to the anodes of the subsequent cell. Also disclosed is a bipolar electrolyzer containing a plurality of individual electrolytic cells electrically and mechanically in series. Each of the cells have anodes and cathodes, with the cathodes of one cell being separated from the anodes of the next adjacent cell in the electrolyzer by a backplate. The electrolyzer is characterized in that the backplate has separate anodic and cathodic members with the anodic and cathodic members being spaced from each other, and conductor means which are offset from both the anodes and the cathodes of the cell. In this way the electrical current changes direction four times, i.e., the electrical current must pass from the cathodes of the first cell laterally thereto, to conductor means and then from the conductor means, laterally thereto, to the anodes of the subsequent cell in the electrolyzer.
