A bipolar plate for a fuel cell is provided to prevent a distortion phenomenon of a separator by applying uniform pressing force to an entire separator during a stamping step. Bipolar plates(100) for a fuel cell are disposed on both surfaces of a thin-film electrode assembly and have every gas channel(120) for supplying hydrogen and oxygen, and a separator(110) for preventing a direct contact between hydrogen and oxygen, wherein the gas channels and separator are integrally formed of a metal material. The separator has a groove(140) with the same width and depth as the gas channels, which is formed along the edges of the separator. |
