An electrolysis device for the electrolytic treatment of liquids has an anode chamber and a cathode chamber which are separated from one another via an ion exchange membrane. The chambers are provided with an inlet opening and an outlet opening for the flowing electrolyte, each with one electrode. The inner space of the anode chamber and/or of the cathode chamber are/is subdivided by webs or ribs extending transversely with respect to the electrodes. The webs or ribs are provided at least regionally with holes or cut outs. The webs or ribs include at least one lower region free of holes or cut outs. The electrolysis device provides sufficient mixing in the upper foam phase in the longitudinal direction and also at the same time the airlift pump effect is maintained by way of ascending gas bubbles in the lower region.

Electrolysis device

An insulating frame for electrolysis cells is proposed, which has a geometric form with corners, said insulating frame being of a flat design and having an anode and a cathode side as well as an outer and inner end face, the insulating frame being characterized in that it is has an edge area directly adjoining the inner end face, characterized in that in the area of the corners the edge area has corner expansion joints in the form of cut-outs.

Insulating frame with corner expansion joints for electrolysis cells

The present invention concerns a method of retrofitting of a membrane electrolysis cell, wherein a rigid cathode is shaped by plastic deformation of the regions in correspondence of cathodic supports; a pre-shaped conductive elastic element having compressed regions in correspondence of said cathodic supports is overlaid onto said rigid cathode; a flexible planar cathode provided with a catalytic coating is overlaid onto said conductive elastic element. The invention also concerns a correspondingly retrofitted electrolysis cell.

Method of retrofitting of finite-gap electrolytic cells

What is proposed is an apparatus for conducting an electrolysis with an oxygen depolarized cathode, comprising: (a) an electrolyzerwhich (b) is connected on the reactant side via an inlet control valveto an oxygen source, and (c) on the product side has at least one off gas line, (d) which has at least one pressure regulator (PT), at least one gas analyzer (QI), at least one flow regulator (FT)and at least one outlet control valve, wherein (e) the pressure regulatorcontrols the inlet control valve, (f) the gas analyzercontrols the flow regulatoror the outlet control valveand/or (g) the flow regulatorcontrols the outlet control valve

Apparatus and method for operating an electrolysis with an oxygen depolarized cathode

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.
