Metal sheet profiled proton exchange membrane fuel cell bipolar plate

The invention relates to a fuel-cell bipolar plate of proton exchange membrane by metal veneer forming, belonging to a fuel cell technical field, comprising two same flow-field veneers. The inventionis characterized in that: the two same flow-field veneers are respectively used as an anode and a cathode, and the two same flow-field veneers are connected together by a peripheral interface and a middle flow-field interface and welded together via symmetrical joint; three inlets and three outlets are arranged on each flow-field veneer and respectively are a fuel gas inlet, a fuel gas outlet, anoxidant inlet, an oxidant outlet, a coolant inlet and a coolant outlet; a plurality of rounded locating holes are respectively arranged at the middle of the two sides. The invention has the advantagesof simpler structure for only two same metal veneers, lower manufacturing cost for only a forming die, using special design of only adding sealing rings to a couple of inlet and outlet to the inletsand the outlets of the reaction gases and reducing use time of the sealing rings.
