Abstract

In einer elektrolytischen Zelle für die Elektrolyse von wässrigem halogenidhaltigem Elektrolyt mit monopolaren Anfangs- und Endeinheiten und jeweiligen Stromführungse­ lementen zwischen Stromsammelschienen und Anfangs- bzw. Endeinheiten und mit einer Vielzahl von bipolaren Elektrodeneinheiten je mit einem anodischen und kathodi­ schen Teilelement als Elektrodenpaar in fluchtender, verbun­ dener Anordnung sind Anodenteilelement und Kathodentei­ lelement an den zugewandten Ende auf ihre aktiven Länge mittels eines bipolaren Stromführungselementes elektrisch leitend verbunden. Die Verbindung für die Leitung des elektrischen Stromes muß eine beständige elektrische Ver­ bindung sein bei möglichst kurzen Verbindungswegen. In an electrolytic cell for the electrolysis of aqueous halide electrolyte with monopolar Start and end units and respective current routing elements between busbars and start or end units and with a variety of bipolar Electrode units each with an anodic and cathodic sub-element as a pair of electrodes in aligned, connected whose arrangement are anode element and cathode part l element at the facing end to their active length electrically by means of a bipolar current-carrying element conductively connected. The connection for the management of the electrical current must have a constant electrical ver be binding with the shortest possible connection paths.

Die geschieht erfindungsgemäß dadurch, daß die Stromführungselemente Bimetall-Einheiten sind, die durch plastische Verformung im Kontaktbereich der beiden Metalle hergestellt sind. This happens according to the invention in that the Current carrying elements are bimetallic units that pass through plastic deformation in the contact area of the two metals are made.
