Abstract: A metallic bipolar plate for a fuel cell includes a cathode plate and an anode plate, each stamped from an individual metal sheet, wherein: the cathode plate and the anode plate are closely combined in a back-to-back manner, and the grooves and ridges at the back sides of the plates are such designed in terms of width, depth and direction that they can form the coolant flow channel directly, the cathode plate and the anode plate are back-to-back combined by a frame-shaped gasket sandwiched between frames of the plates, the grooves and the ridges at the back sides of the two plates, when coupled, jointly form the coolant flow channel having a groove-to-groove or groove-to-ridge structure, thereby constructing the bipolar plate having three flow channels from the two plates, wherein, the frame-shaped gasket only received in the frame-shaped hollow space around the flow field formed between the stamped plates.
