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.

Cell structure for electrolyzer units and fuel cells

A method of separating certain components of a gas mixture in which the gas mixture is cooled and certain components are separated in a liquid or solid state characterized by introducing the gas mixture into a separator tank, adding a cooling agent such as a liquid or cold inert gas so as to cool the gas mixture and separating component in a solid state and subsequently fusing the separated solid into a liquid in a collecting tank. The concentrated gas mixture to be separated is directly removed from its place of use and directly supplied to the separator tank without allowing any further admixture of secondary air. The device for carrying out the method comprises an insulated tank to which air having entrained sulfer dioxide is introduced. The air flow is controlled so that it is oriented in a particular direction and it is passed beyond nozzles for injecting an inert gas such as liquid nitrogen into the interior of the insulated tank. This causes the component to form a solid substance in the form of a snow which is subsequently recovered at the lower end of the tank in an insulated collecting tank portion which advantageously includes means to heat the substance to form it into a liquid.
