Abstract

The invention proposes a method for connecting plate-like components of a bipolar plate, comprising the steps of placing a first plate-like component on a clamping surface, placing a second plate-like component onto the first plate-like component, fitting a plurality of hold-down devices on an outer surface of the second plate-like component, said outer surface facing away from the first plate-like component and the clamping surface, wherein an envisaged seam line is kept free between the hold-down devices, pressing of the plate-like components together using all of the hold-down devices, wherein, for this purpose, a magnetic force acting in the direction of the clamping surface is applied to at least one of the hold-down devices, and welding the plate-like components along the seam line in a continuous operation.
