Abstract: An electrolysis plate, in particular for the electrolysis of water, including a rectangular profiled metal sheet which has two long sides and two narrow sides and which has an outer, frame-like connecting region and a profiled region which is located within said connecting region, has a rectangular, non-square basic shape and forms an active area. A flow channel having a longitudinal direction defined by the non-square shape of the profiled region and running parallel to the long sides is delimited by the surface of the profiled region. An embossed pattern of the profiled metal sheet is provided successively in the longitudinal direction of the profiled region at least three times, not overlapping or touching, i.e. spaced apart. Each embossed pattern is formed by at least three individual embossed patterns positioned adjacent to one another, extending in the longitudinal direction and describing a zigzag or undulating shape.
