Bipolar plate of air-cooled fuel cell

The utility model discloses an air-cooled fuel cell bipolar plate which is used for solving the problems that an air-cooled hydrogen fuel cell bipolar plate in the prior art is relatively large in weight and relatively low in air utilization rate and reaction efficiency. The bipolar plate comprises a bipolar plate substrate, one side of the bipolar plate substrate is an anode reaction surface, and the other side of the bipolar plate substrate is a cathode reaction surface; the hydrogen inlet and the hydrogen outlet penetrate through the bipolar plate base body, the hydrogen flow channel is communicated with the hydrogen outlet/inlet, the hydrogen flow channel is a continuous baffling channel, and the first sealing piece surrounds the outer side of the hydrogen outlet/inlet and the outer side of the hydrogen flow channel; a plurality of groove channels which longitudinally penetrate through the upper side and the lower side of the cathode reaction surface are uniformly arranged on the cathode reaction surface,
