摘要： 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 (4) , a cathode (5) and an ion exchange membrane (1) arranged between the electrodes. Spacer elements (2,3) 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 .

摘要： Electrolysis cell in the constructive form of single elements, intended for instance for the production of chlorine, hydrogen and/or caustic soda and designed in such a way that the portion of inactive membrane surface is minimised thanks to an optimised flange type so that the ratio between the flange surface of a semi-shell and the active membrane surface can be set to less than 0.045, neither the semi-shells nor the membrane being provided with bores or recesses for accommodating the clamping members.

摘要： The invention relates to an electrolysis cell of the single-element type design for chlor-alkali electrolysis plants, comprising an anode compartment and a cathode compartment, each of the two compartments containing an electrode connected to the rear wall of the respective compartment by means of parallel bars. The electrodes are thus subdivided into several sections. In accordance with the invention, at least one of two electrodes is provided with a curved shape in each section, this curved section protruding towards the opposite electrode and pressing a membrane area against the opposite electrode. According to a preferred embodiment, the curved shape of the various electrode sections is obtained by means of springs.

摘要： The invention relates to an electrode for electrochemical processes for gas production, which in the installed state is located parallel and opposite to an ion exchange membrane and consists of a multitude of horizontal lamellar elements which are structured and three-dimensionally shaped and are in contact with only one surface with the membrane, wherein the lamellar elements have grooves and holes, the major part of the holes being placed in the grooves and the surfaces of such holes or part thereof are located in the grooves or extend into the grooves. In such a way the holes are ideally placed in the contact area of the respective lamellar element with the membrane.
