An electrode of an electrolysis cell for gas-producing electrochemical processes, which includes a plurality of horizontal lamella elements which in the manner of a flat C-profile consist of a flat central part and one or more flank parts, where one or more transition regions of any shape are arranged between the flat central part and the one or more flank parts, where the lamella elements have a plurality of through-openings, where the lamella elements have a flat surface without structural raised regions and depressions and the flat central part has a plurality of through-openings which are arranged in rows and arranged diagonally to one another.

Electrode for electrolysis cells

A method for coating a substrate on one or more sides having catalytically active material producible by material deposition under vacuum in a vacuum chamber, using the following steps: loading a substrate in the chamber evacuating the chamber, cleaning the substrate by introducing a gaseous reducing agent, removing the gaseous reducing agent, applying an intermediate layer by means of vacuum arc evaporation, wherein a substrate comprising the same or similar material is introduced into the vacuum chamber, controlling the chamber temperature, coating by vacuum arc evaporation, a metal taken from the group ruthenium, iridium, titanium and mixtures thereof while oxygen is supplied, in a last step the coated substrate is removed from the chamber, wherein at least 99% of the substrate coating is free of constituents originally contained in the substrate itself, and at least 99% of the coating applied on the intermediate layer is kept free of non-oxidized metals.

Substrate coating on one or more sides

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.

Electrolysis cell

The invention relates to an electrolysis device for cleaning acidic waters which comprises a cathode, an anode, and an ion exchange membrane, wherein the membrane is arranged between the cathode and the anode and is attached at least along the entire circumference of its rim, wherein many inlets and outlets are arranged along the upper and lower rim of the electrolysis device which are linked to the cathode space or to the anode space, in such a way that a plug flow, ideally with a laminar profile, is created in the cathode space and in the anode space.

Device for electrochemical water preparation

The invention relates to an insulating frame of an electrolysis cell having a microstructured internal section allowing the penetration of the electrolyte even if the structured section is partly or completely overlapped by the membrane, and to an electrolysis cell equipped with the same.
