ELECTROLYSIS CELL

The invention relates to an electrolysis cell (1) for chlor-alkali or alkaline water electrolysis comprising two cell elements (2) each defining an electrode chamber (3) by providing a back wall (4) and sidewalls (5) of the electrode chambers (3), and a sheet-like separator (6) being interposed in a joint (7) between the two cell elements (2) and providing a separating wall (8) between the electrode chambers (3), wherein an electrode (9) and an electrode support unit (10) is accommodated in each of the electrode chambers (3), wherein the electrode support units (10) provide an electrical connection between the back wall (4) and the electrode (9) in each of the electrode chambers (3), wherein the electrodes (9) are in direct contact with the sheet-like separator (6), and wherein at least in one of the electrode chambers (3) the electrical connection between the back wall (4) and the electrode support unit (10) and/or between the electrode support unit (10) and the electrode (9) is provided by means of a surface contact connection (11).
