The present invention relates to a bipolar plate for fuel cells, comprising at least a shaped, at least partially electrically conductive foil (), the bipolar plate having a channel structure () formed by the shaping of the foil (), to convey reactants to electrodes of adjacent fuel cells and to carry away reaction products, and a microstructure () is integrated into the foil () to increase the rigidity of the foil (). The invention also relates to a method for manufacturing corresponding bipolar plates.

Bipolar plate for fuel cells, which is formed from a shaped foil, and method for manufacturing same

The present invention relates to bipolar plate () as well as to a fuel cell assembly (). The bipolar plate comprises two outer surfaces () which are electrically connected to one another, for the electrical contacting, as well as the discharge and supply of gases and/or fluids to the surfaces of the fuel cells which are adjacent to the outer surfaces. The bipolar plate comprises a frame () open in the central region as well as an inner part () arranged in the central reign, wherein the frame and the inner part are elastically connected to one another.
