Abstract
A cell structure for electrolyzer units and fuel cells, comprising an electrolyte-permeable diaphragm, one metallic, electrolyte-permeable electrode respectively on either side of the diaphragm, an electrically conductive bipolar cell partition respectively which bounds the cell, one electrically conductive structure respectively between the electrode and the cell partition which acts as an elastic spacer and current supply, and a frame construction which encloses the cell on the circumference side. The diaphragm is constructed as a flat plate, with layer-type electrodes resting directly on it and integrally connected with it. The cell partitions are constructed of sheet metal, if necessary, with spacers. The spaces between the electrodes and the cell partitions are at least partially filled with lamellar structures which are axially and perpendicularly fluid-permeable and rest against the electrodes. The lamellar structures consist of a plurality of wall elements which are arranged at a narrow distance and have interposed spacers.
