Abstract: Electrolysis stack, including multiple layers that are stacked along a stacking direction, wherein each of the layers includes an anode space with an anode, a cathode space with a cathode and a membrane that separates the anode space and the cathode space from each other, wherein the anode space, the membrane and the cathode space are arranged adjacent to each other in the stated order along the stacking direction, and wherein each of the layers further includes a respective electrically insulating shell that surrounds the anode space and the cathode space so as to enclose the anode space and the cathode space radially with respect to the stacking direction, wherein the shell includes a groove on at least one of its end faces in the stacking direction, wherein the groove surrounds the anode space and the cathode space at least partially.

Abstract: The invention relates to a stack of several electrochemical cells stacked on top of one another in a stacking direction. The stack comprises at least: a first electrochemical cell, a second electrochemical cell, and an intercalary plate. Each cell includes an upper frame housing a first electrode and a lower frame housing a second electrode, the first electrode and the second electrode being separated from one another by a membrane. The second electrode of the first electrochemical cell and the first electrode of the second electrochemical cell are separated by an intercalary plate. The stack includes an intercalary frame arranged on the periphery of the intercalary plate.
