The invention relates to a lotus leaf-like bionic bipolar plate, a self-drainage method thereof and a fuel cell. The lotus leaf-like bionic bipolar plate comprises a bipolar plate main body, a runner ridge part, a runner, a shunting runner, a converging runner, an air inlet and an air outlet, micro-flow fields which are uniformly distributed are arranged on the flow channel; the micro-flow field comprises lotus leaf-like mastoid structures which are uniformly distributed. According to the lotus-leaf-like bionic bipolar plate, the micro-flow field is arranged in the flow field and the lotus-leaf-like mastoid structure is arranged in the micro-flow field, so that water generated by reaction cannot infiltrate the interior of the flow field, but is separated into water drops by the lotus-leaf-like mastoid structure to be discharged out of the bipolar plate in a sliding manner, and the drainage efficiency is improved; and the water logging phenomenon of the fuel cell is reduced. 本发明涉及类荷叶仿生双极板及其自排水方法和燃料电池，所述类荷叶仿生双极
