The invention relates to a bipolar plate for fuel cells, a fuel cell stack with the bipolar plate, and a vehicle, specifically, in order to provide a bipolar plate for a fuel cell, provide an anode plate with an anode side and a coolant side, wherein a first structuring for forming an anode flow field is formed on the anode side, and a cathode plate with a cathode side and a coolant side, whereina second structuring for forming a cathode flow field is formed on the cathode side; wherein structural elements, which are contacted by the coolant sides of the anode plate and the cathode plate, forforming a coolant flow field, are arranged between the anode plate and the cathode plate, which bipolar plate has an optimized pressure distribution in a fuel cell stack and increased stability in comparison with the prior art, it is proposed that the structural elements may be made of an elastic material and that the structural elements have a different height in different regions of the coolantflow field. A fuel cell stack and a vehicle are also disclosed.

    本发明涉及燃料电池的双极板,带有双极板的燃料电池堆垛以及车辆,具体而言为了提供用于燃料电池的双极板,其提供带有阳极侧和冷却介质侧的阳极板,其中,在阳极侧上构造有用于构造阳极流场的第一结构部,和带有阴极侧和冷却介质侧的阴极板,其中,在阴极侧上构造有用于构造阴极流场的第二结构部;其中,在阳极板与阴极板之间为了构造冷却介质流场布置有结构元件,其被阳极板和阴极板的冷却介质侧接触,其相对于现有技术具有在燃料电池堆垛中优化的压力分布和更大的稳定性,提出如下,即结构元件由弹性材料组成并且结构元件在冷却介质流场的不同区域中具有不同的高度。此外公开了一种燃料电池堆垛和车辆。
