Abstract:
An electrolysis cell includes an anode chamber and a cathode chamber separated by an ion-exchange membrane. The electrolysis cell includes an anode, a cathode, and a cathode current distributor. The anode, the ion-exchange membrane, the cathode, and the cathode current distributor are in direct touching contact in the mentioned order. Flexibly resilient holding elements are arranged on the other side of the anode and/or on the other side of the cathode current distributor. The flexibly resilient holding elements exert a contact pressure on the anode and/or on the cathode current distributor. The flexibly resilient holding elements have annular elements, the axis of which is oriented in the height direction of the electrolysis cell. By means of the flexibly resilient and in part also plastically deforming annular elements, effective mechanical contact pressure of the ion-exchange membrane against the oxygen-depolarized cathode is achieved.
