The invention discloses a fuel cell stack, a fuel cell system and a vehicle. The technical problem that the cost is increased due to the fact that a fastening scheme is changed is solved. The fuel cell stack comprises a gas inlet end plate and a blind end plate assembly, and further comprises n fasteners and 2n fastening joints, and n is greater than or equal to 2. Wherein the n fasteners are distributed on at least two opposite side surfaces of the fuel cell stack; the fastener is a pull rod and/or a steel belt. The 2n fastening joints are respectively connected to the two ends of the n fasteners; the fastening joint comprises a mounting part and a connecting part which are connected, and the connecting part is connected to the fastener; mounting positions are arranged on the side face of the air inlet end plate and the side face of the blind end plate assembly, and the mounting parts are arranged in the mounting positions and connected to the air inlet end plate or the blind end plate assembly through connecting pieces with projection components in the stacking direction. Universal connection of pull rod type fastening and steel belt type fastening on a pile body is achieved through the fastening connector.
