Demand-based closed-loop control is used in an electrochemical plant that has modules and a control unit, with each module being individually controlled by the control unit and supplied with a module-specific electric operating current. For each module to generate a separate product flow, product flows of the individual modules, connected in parallel, are merged to form a total product flow. When a start condition occurs, the control unit records a current total product flow demand, records a current efficiency of the modules based on a ratio of respective operating current and product flow, determines operationally ready modules, determines module-specific target operating currents for the operationally ready modules to cover the demand from a range of permissible module-specific target operating currents based on the efficiency of the modules and the demand, and sets the operating currents of the operationally ready modules to the determined module-specific target operating currents.

Method for on-demand closed-loop control of an electrochemical plant

A textile can be configured as a spacer between a housing or a supporting structure and an electrode or a substructure of an electrode of a zero-gap electrolytic cell. The textile may comprise a mechanical connection means composed of an elastic polymeric material and may comprise an electrical connection means different from the mechanical connection means. A zero-gap electrolytic cell can be furnished with such a textile. Further, a method for producing such a zero-gap electrolytic cell may be characterized in that at least one ply of a textile is placed into an anode tank or cathode tank, an anode or cathode electrode is disposed on the at least one ply of the textile, an ion exchange membrane is placed onto this electrode, and a cathode electrode or anode electrode connected to a cathode tank or anode tank, respectively, is disposed on the ion exchange membrane.

Use of a textile, zero-gap electrolytic cell and production method therefor

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.

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.
