Electrolysis cell

An electrolysis cell consisting of a housing with one inlet and one outlet for the electrolyte passing through the cell, said housing accommodating monopolar electrodes, each electrode consisting of a number of parallel plates fixed to a common carrier element, the electrodes being arranged in a staggered pattern so that the plates of one polarity extend into the gaps formed by the plates of the opposite polarity and at least one median electrode stack of one polarity with central electric power input is arranged between two electrode stacks of the other polarity, characterized in that the median electrode stack consists of a plurality of electrode plates and a power input plate of a length substantially equal to said plurality of electrode plates and a width substantially equal to that of the cell;

• said electrode plates being welded along one longitudinal side to said power input plate in a toothed pattern and said power input plate being joined to one side of wall of said cell housing and being provided with at least one power input connection.
