The invention discloses a fastening assembly, a fuel cell module and a vehicle. The fastening assembly comprises a shell and more than two cross beams arranged in the shell; the two or more cross beams are located at one end of the shell, and the two ends of the two or more cross beams are limited through the shell, so that the shell applies fastening force to an electric pile of the fuel cell in the stacking direction through the cross beams, and box body packaging is achieved. The press-fitting force of the press is transferred through the plurality of cross beams arranged at one end of the galvanic pile, the plurality of cross beams distributed at intervals form a limiting surface to jointly apply fastening force to the galvanic pile, and the stress distribution of the galvanic pile is uniform. As the cross beams are distributed at intervals, the intervals can be used for the pressing head of the pressing machine to penetrate through, and the pressing operation of the pressing machine is not affected.
本申请公开了一种紧固组件、燃料电池模块以及车辆。紧固组件包括壳体和设于壳体内的两根以上横梁;两根以上横梁位于壳体的其中一端,两根以上横梁的两端均通过壳体限位,以使壳体通过横梁向燃料电池的电堆施加沿堆叠方向的紧固力,实现箱体封装。通过设置在电堆一端的若干横梁转移压机的压装力,间隔分布的若干横梁形成一个限位面,共同向电堆施加紧固力,电堆受力分布均匀。由于各个横梁间隔分布,其之间间隔可用于压机的压头穿过,不会影响压机压装操作。
