Abstract

The invention relates to an electrolytic cell for the production of chlorine from an aqueous alkali halide solution, which mainly consists of two semi-shells, an anode, a cathode and an ion exchange membrane arranged between the electrodes. Spacer elements are arranged between the ion-exchange membrane and the electrodes for fixing the membrane in position and distributing the compressive forces, made of electrically conductive and corrosion-resistant material on at least one side of the membrane.
