The invention provides a bipolar plate for a fuel cell, the fuel cell and a vehicle. The bipolar plate for the fuel cell comprises an outlet distribution area, a main flow field area and an inlet distribution area, the outlet distribution area and the inlet distribution area are respectively arranged on two sides of the main flow field area; the main flow field area is provided with a plurality of bosses; the bosses are distributed in the fluid flowing direction of the main flow field area, and the density of the bosses is gradually increased in the fluid flowing direction. The density of the bosses is gradually increased in the fluid flowing direction, the bosses at different intervals are arranged, and the bosses are dense at the outlet end, so that the drainage capacity of the tail end of the polar plate is improved, the water logging phenomenon is reduced, and water at the tail end of a galvanic pile is more easily drained.
本发明提供了一种用于燃料电池的双极板、燃料电池及车辆。其中,用于燃料电池的双极板,包括出口分配区、主流场区和入口分配区;所述出口分配区和入口分配区分别设置在主流场区的两侧;所述主流场区设置凸台,所述凸台为多个;多个凸台沿主流场区流体流动方向分布,且凸台设置的密度沿流体流动方向逐渐增大。通过凸台设置的密度沿流体流动方向逐渐增大,设置不同间距的凸台,在出口端凸台较密,从而提高极板末端的排水能力,降低水淹现象,使电堆末端的水更容易排出。
