Sealed electrolysis cell

An electrolysis cell, comprising:

• a first element including a first circumferential flange portion and a first central portion delimiting an anode chamber;
• a second element including a second circumferential flange portion and a second central portion delimiting a cathode chamber;
• an anode accommodated in the anode chamber;
• a cathode accommodated in the cathode chamber;
• a sheet-like separator having a circumferential edge, the separator disposed between the first and second elements and separating the anode and cathode chambers;
• and
• a sealing arrangement including a first gasket and a second gasket, wherein the sealing arrangement is disposed in a gap between the first and second circumferential flange portions for fastening the separator and for sealing the anode chamber and the cathode chamber;
• wherein the first gasket is an inner gasket positioned in a portion of the gap adjacent to the chambers and the second gasket is an outer gasket positioned in a portion of the gap distant to the chambers;
• wherein the gaskets are spaced apart from each other in the gap at an interval and the separator is fastened in the cell by the first gasket, and wherein the circumferential edge of the separator is located radially between a midpoint of the first gasket and a midpoint of the second gasket;
• wherein the sealing arrangement further includes an electrically isolating layer disposed in the gap such that a first side of the layer is in contact with the first gasket and a second, opposite side of the layer is in contact with the second gasket.
