Abstract
The various embodiments of the present invention disclose a pressurized alkaline electrolyser stack, comprising: a stack core (100a) comprising a plurality of electrolysis cells (200), wherein each electrolysis cell (200) comprises an anode chamber comprising an anode, a cathode chamber comprising a cathode, a diaphragm (206) separating the anode chamber and the cathode chamber, at least one cell frame (201) and at least one gasket (202). The stack core (100a) is configured to have a first stack core length L<sub>1</sub> and a first gasket stress σ<sub>1</sub> at a first design temperature T<sub>1</sub> and a second stack core length L<sub>2</sub> and a second gasket stress σ<sub>2</sub> at a second design temperature T<sub>2</sub>. The first design temperature T<sub>1</sub> is at least 80 degrees Celsius and the second design temperature T<sub>2</sub> is less than 30 degrees Celsius. A stack core length difference dL = L<sub>1</sub>-L<sub>2</sub> is between 0 to 20 millimeters, and a gasket stress difference dσ =σ<sub>1</sub>-σ<sub>2</sub> is between 0 to 20 MPa.
