Flow type electrochemical cells are disclosed. The electrochemical cell has an anode half-cell, a cathode half-cell, and permeable separating layer. The half-cells are bounded by side elements. Respective porous electrodes are housed in the half-cells. The permeable separating layer is disposed between the anode half-cell and the cathode half-cell. An electrolyte region connected to an electrolyte feed and an electrolyte outflow region connected to an electrolyte drain are further provided. An electrolyte inflow region and an electrolyte outflow region are disposed on opposite sides of the porous electrodes such that inflowing electrolyte flows through the porous electrode perpendicularly to the permeable separating layer.

Flow-type electrochemical 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 a method for producing electrically conducting nickel oxide surfaces made of nickel-containing material. According to the method, the nickel surface is first degreased and is then roughened for approximately ten minutes in a solution containing about one percent of hydrochloric acid, the process being accelerated by adding hydrogen peroxide solution, resulting in the electrolyte turning green. The nickel surface is briefly wetted, the nickel material is introduced into a solution of 3.5 molar lye to which about ten percent of hydrogen peroxide is added and is kept therein for ten minutes, and the resulting nickel hydroxide surface is dehydrated in a subsequent thermal process and is then further oxidized to obtain nickel oxide. The invention further relates to a conductive boundary layer that is produced according to the method, the electrodes therefrom, and the use thereof in chlorine-alkali electrolysis processes, in fuel cells and storage batteries.

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.
