The invention provides a hydrogenation control method and device of a fuel cell, a fuel cell system and a vehicle. The hydrogenation control method of the fuel cell comprises the following steps: when it is identified that the fuel cell needs hydrogenation, controlling a DCDC module of a fuel cell system to reduce an output current according to a set slope, and controlling the output current of the DCDC module within a set range; enabling the pressure of a hydrogen cavity of the fuel cell to reach Ph2 and the pressure of an air cavity to reach PAir, and then carrying out hydrogenation on the fuel cell. By identifying the hydrogenation process, the output current, the air path pressure and the hydrogen path pressure of the fuel cell system are controlled, and a hydrogen-oxygen interface is avoided, so that the purpose of prolonging the service life of the fuel cell is achieved.
