ELECTROLYSIS CELL WITH A HIGH ELECTRIC CURRENT CAPACITY FOR PRODUCING AN OZONE-OXYGEN MIXTURE

摘要

The invention relates to an electrolysis cell which consists of a basic electrode body (1) of impregnated graphite, on the cathode side of which the cathode gaps are incorporated in the form of vertical cathode channels (2), which are connected at the top and at the bottom by a transverse channel. At the same time, the ribs bring about the electrical contact with the gas diffusion layers (3) (GDL), which have been pressed on there. If the GDL are activated appropriately, oxygen reduction takes place cathodically. Sealing frames (4) of a flexible plastic seal the GDL at the sides. The anode and cathode gaps are separated by solid electrolyte cation exchange membranes (5). On the anode side, the punctured, structured anode plates (6), which consist, for example, of a diamond-coated niobium expanded metal, are pressed against the membrane. They are bonded in hard frames (7), for example, of PVC-C and contacted by contacting elements (8) with the adjoining basic graphite body, which is protected by insulating films (9) of PTFE from corrosion by ozone. The contacting mechanisms for the anode plates are integrated in the anode sides of the basic electrode bodies. They consist of flexible intermediate layers (10) and rigid contacting plates (11), as well as of the contacting tubes (12).
