Abstract: An electrolytic cell may include a cathode half-cell having a cathode, an anode half-cell having an anode, and a separator that separates the two half-cells from one another and that is permeable to electrolyte present in the half-cells during operation. At least one inlet for electrolyte is provided in a first half-cell of the two half-cells, and at least one outlet for electrolyte and no inlet for electrolyte are provided in the second half-cell such that electrolyte supplied via the at least one inlet is dischargeable via the at least one outlet after passing through the separator. A method can also be utilized to operate such an electrolytic cell. And an electrolyzer may include multiple of such electrolytic cells.

Abstract: An electrolyzer including an electrolysis stack containing a plurality of panel-like electrolysis cells in a side-by-side arrangement and being electrically interconnected in series, wherein each electrolysis cell comprises an anode chamber with an anode arranged therein and a cathode chamber with a cathode arranged therein, wherein the anode chamber and the cathode chamber are separated from one another by a sheet-like separator. The electrolyzer having means for mechanically securing the electrical interconnection of the electrolysis stack. The stack contains at least two multi-cell elements, each including a plurality of the electrolysis cells and mechanical compression means, wherein the electrolysis cells of each multi-cell element are held together in a sealed manner by the mechanical compression means and wherein the means are configured to mechanically secure the electrical interconnection of the multi-cell elements.
