Abstract
The present application relates to an electrolytic cell comprising at least a first and a second bipolar plate (14) and an electrode unit (1216a, 1216b) and a membrane (11). The electrode unit comprises a planar electrode (12a, 12b) and a sandwich (16a, 16b) which is elastically deformable in a direction orthogonal to the planar electrode (12a, 12b) and which has a thickness which is greater than the thickness of the electrode (12a, 12b) at least in a central region of the sandwich (16a, 16b), the sandwich (16a, 16b) comprising a peripheral region which is flattened in said direction and which is connected to the periphery of the electrode (12a, 12b) by a weld resulting from a self-fusion welding. The present application also relates to an electrolytic cell stack comprising such an electrolytic cell and to a method for manufacturing such a stack.
