description The invention belongs to the technical field of fuel cells, and discloses a cathode open type air-cooled fuel cell bipolar plate, which comprises a bipolar plate body, and the two surfaces of the bipolar plate body are respectively an anode side and a cathode side; a hydrogen gas channel and a cathode flow field are arranged on the cathode side; the cathode flow field comprises a plurality of straight flow channels parallel to the width direction of the bipolar plate body, and each straight flow channel penetrates through the width direction of the cathode side; a plurality of baffles are fixedly arranged in each straight flow channel at equal intervals, and each baffle is perpendicular to the width direction of the bipolar plate body and is used for reducing the cross sectional area of the corresponding straight flow channel. The baffles are arranged in the cathode flow channel at intervals and are staggered with the baffles of the adjacent flow channel, so that the transmission efficiency of air to the cath
