Abstract:
1. An electrolysis cell of single-element type design for chlor-alkali electrolysis comprising: an anode compartment and a cathode compartment, each delimited by a rear wall, each of said two compartments having a corresponding electrode arranged therein consisting of an anode being arranged in said anode compartment and a cathode being arranged in said cathode compartment; a membrane arranged between the electrodes, each of said electrodes being connected with the rear wall of the respective compartment by means of parallel bars, said bars subdividing the corresponding electrode into multiple sections, each section having at least one of the electrodes in a pre-formed curved shape such that the curved portion is protruding towards the opposite electrode and defining a vertex line, the pre-formed curved shaped electrode is arranged so as to press an area of the membrane against the opposite electrode, the area being a width running on two sides of the vertex line and being at least 20% of the width of said section, wherein the number of said curved portions coincides with the overall number of sections of the corresponding cell compartment.
