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.
