The invention discloses a fault processing method and device of a fuel cell vehicle system and a vehicle, and relates to the technical field of vehicle control. A specific embodiment of the method comprises the following steps: in response to detection of a fault of a storage battery, controlling a fuel cell converter, a boost converter and a vehicle auxiliary engine except a low-voltage buck converter and a storage battery temperature control box to stop running; controlling the fuel cell to continue to operate, so that the fuel cell directly supplies power to the load; the first inverter, the second inverter, the step-down converter, the fuel cell auxiliary machine, the low-voltage step-down converter and the storage battery temperature control box are controlled to stop running; a relay of the storage battery is cut off; the boost converter, the buck converter, the fuel cell auxiliary machine, the vehicle auxiliary machine, the first inverter and the second inverter are controlled to be started again, so that the vehicle enters the limping mode; and detecting whether the relay is sintered. The fault processing method of the fuel cell vehicle system can respond to the driving demand of the user as soon as possible.
