    Abstract: The invention relates to a bipolar plate for PEM fuel cells, comprising an internal metal layer and two non-conducting plastic layers, arranged on both sides of and surrounding the metal layer and forming the surfaces of the bipolar plates. The metal layer comprises one or several electrically conducting connections with both surfaces and the plastic layers comprise surface channels for gas transport. The invention further relates to a bipolar plate for PEM fuel cells made from a non-conducting plastic with channels for gas transport on both surfaces and which is metal-coated except in the peripheral regions. The metal coatings on both sides are electrically connected by means of one or several metal contacts extending through the plastic.

    Abstract: Described are a bipolar plate for PEM fuel cells comprising a core metal layer and two nonconductive plastic layers bilaterally overlying the metal layer and enclosing it, which form the surfaces of the bipolar plates, wherein the metal layer has one or more electroconductive connections to both surfaces and the plastic layers are equipped with superficial gas transport channels, and a bipolar plate for PEM fuel cells made of nonconductive plastic which is equipped on both surfaces with gas transport channels and which, except for its edge region, is metal coated, the bilateral metal coatings being electroconductively connected through the plastic via one or more metal contacting means.
