Bipolar plate of hydrogen fuel cell

The utility model discloses a bipolar plate of a hydrogen fuel cell, which is used for solving the problems of large weight and large volume of the bipolar plate of the hydrogen fuel cell in the prior art. The bipolar plate comprises a bipolar plate substrate made of a non-metallic material, a conductive layer is arranged on the surface of the 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 anode reaction surface is provided with a hydrogen inlet/outlet, a hydrogen flow channel communicated with the hydrogen inlet/outlet and a first sealing element, the hydrogen flow channel is a continuous baffling channel, and the first sealing element surrounds the outer sides of the hydrogen inlet/outlet and the hydrogen flow channel; and a plurality of air flow channels are uniformly arranged on the cathode reaction surface. The conductive layer is arranged on the non-metal substrate, so that the conducti
