The invention discloses a stack fastening device, a fuel cell stack and a vehicle, and solves the technical problem of non-uniform fastening force caused by deformation of an end plate in the prior art. The galvanic pile fastening device comprises a pressing plate and a fastening rod, and the pressing plate is located on the outer side of a first end plate of a galvanic pile so as to apply acting force to the galvanic pile in the stacking direction; the plurality of fastening rods are arranged at intervals, each fastening rod is provided with a first end and a second end, the first end is connected to the pressing plate, and the second end is used for being connected to a second end plate of the electric pile. The fastening rod firstly acts on the pressing plate, and then the pressing plate acts on the first end plate, so that the acting area between the pressing plate and the first end plate is large, the first end plate is not easy to deform, the fastening force of the electric pile is uniformly distributed, and the risks of performance reduction and reactor core sealing failure caused by non-uniform stress of the single battery and the reactor core are reduced.

    本申请公开了一种电堆紧固装置、燃料电池电堆及车辆,解决现有技术端板变形导致紧固力不均匀的技术问题。本申请提供的电堆紧固装置包括压板和紧固杆,其中,压板位于电堆的第一端板的外侧,以向所述电堆施加沿堆叠方向的作用力;紧固杆设有多个,多个紧固杆间隔设置,紧固杆设有第一端和第二端,第一端连接于压板,第二端用于连接于电堆的第二端板。本申请中由于紧固杆先作用于压板,压板再作用于第一端板,因此压板与第一端板之间的作用面积大,第一端板不易变形,电堆的紧固力分布均匀,降低单电池及堆芯因受力不均导致的性能下降和堆芯密封失效的风险。
