The bipolar plate comprises a cathode plate and an anode plate, the cathode plate is provided with a cooling flow field for guiding cooling liquid, the cooling flow field comprises a main cooling flow field area, the main cooling flow field area is provided with a plurality of cooling flow channels, the cooling flow channels are in a bent shape, and the flowing distances of the cooling liquid in the cooling flow channels are equal. According to the bipolar plate disclosed by the invention, the flow distances of the cooling liquid in the flow channels are equal in length through a forced guide mode, so that the pressure drop of each cooling flow channel is consistent, the flow uniformity is improved, the temperature of a reaction area of hydrogen and air is uniform, and the performance and reliability of electric pile power generation are improved. The invention also discloses a fuel cell stack, application of the bipolar plate in the fuel cell stack and a vehicle.

    本发明公开了一种双极板,包括阴极板和阳极板,所述阴极板上设置引导冷却液的冷却流场,冷却流场包括主冷却流场区,主冷却流场区设置多个冷却流道,冷却流道为弯折形状,各个冷却流道中冷却液的流动距离等长。本发明的双极板,通过强制引导形式,使得冷却液在流道中的流动距离等长,从而使得各冷却流道压降一致,提高了流动均匀性,从而使得氢气与空气的反应区温度均匀,提升电堆发电的性能及可靠性。本发明还公开了一种燃料电池电堆、一种双极板在燃料电池电堆中的应用和一种车辆。
