METHOD FOR PRODUCING A METALLIC BIPOLAR PLATE, BIPOLAR PLATE AND FUEL CELL STACK AND METHOD FOR PRODUCING SAME

摘要

The invention relates to a method for producing a metallic bipolar plate (01) for a fuel cell stack, such a bipolar plate, a fuel cell stack and a method for producing same. The bipolar plate has a gas distributor structure (05) on each of the two flat sides of said bipolar plate. According to the invention, the gas distributor structures (05) are produced on both sides simultaneously by partial shearing, wherein grooves (02) and webs (03) with complementary shapes are formed. The bipolar plate is suitable for very simple production of a fuel cell stack.
