Abstract: 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.

Abstract: An oxygen-consuming electrode, in particular for use in chloralkali electrolysis, having a novel catalyst coating and also an electrolysis apparatus are described. Furthermore, its use in chloralkali electrolysis, fuel cell technology or metal/air batteries is described. The oxygen-consuming electrode comprises at least a support which in particular is electrically conductive, a layer containing a catalyst and a hydrophobic layer, characterized in that it contains gallium in addition to silver as catalytically active component.

Abstract: What is proposed is an apparatus for conducting an electrolysis with an oxygen depolarized cathode, comprising: (a) an electrolyzer 1 which (b) is connected on the reactant side via an inlet control valve 2 to an oxygen source 3, and (c) on the product side has at least one off gas line 4, (d) which has at least one pressure regulator (PT) 5, at least one gas analyzer (QI) 6, at least one flow regulator (FT) 7 and at least one outlet control valve 8, wherein (e) the pressure regulator 5 controls the inlet control valve 2, (f) the gas analyzer 6 controls the flow regulator 7 or the outlet control valve 8 and/or (g) the flow regulator 7 controls the outlet control valve 8.

Abstract: Method and system for monitoring the functionality of electrolysis cells for use in chlor-alkali electrolysis.

Abstract: An oxygen-consuming electrode, in particular for use in chloralkali electrolysis, having a novel catalyst coating and also an electrolysis apparatus are described. Furthermore, its use in chloralkali electrolysis, fuel cell technology or metal/air batteries is described. The oxygen-consuming electrode comprises at least a support which in particular is electrically conductive, a layer containing a catalyst and a hydrophobic layer, characterized in that it contains gallium in addition to silver as catalytically active component.

Abstract: An oxygen-consuming electrode is described, more particularly for use in chloralkali electrolysis, comprising a novel catalyst coating, as is an electrolysis apparatus. Also described is a production process for the oxygen-consuming electrode and the use thereof in chloralkali electrolysis or fuel cell technology. The oxygen-consuming electrode is based on a gas diffusion layer as a porous film of a fluorinated polymer, into which fine crystal needles of a catalyst metal have been introduced as the catalytically active component and are connected with electrical conduction to the current collector.
