Abstract

The invention relates to an electrolysis cell for generating ozone or oxygen from superpure water with a solid electrolyte membrane located in a multipartite housing with electrodes designed to be directly connected to the membrane as porous structures, with the membrane separating the cathode space from the anode space and the pressure of both electrodes acting on the membrane being generated by means of a pressure device acting on at least one of the electrodes, with a pressure screw equipped with a convex head being provided as a pressure device, said screw being so arranged that the convex head rests centrally directly on the cathode or anode, and an indentation is pressed into the cathode surface or anode surface by the action of the pressure applied.
