The invention relates to an extended-range air-cooled hydrogen fuel cell hybrid power system and a vehicle. The system comprises a fuel cell system, a super capacitor energy storage system, a bus system, a lithium battery range extending system, a main control system, a first DC-DC conversion module and a second DC-DC conversion module, the super capacitor energy storage system is charged through the fuel cell system; the super capacitor energy storage system is electrically connected with the bus system and the master control system through the second DC-DC conversion module. The lithium battery range extending system is provided with a lithium battery; when the load is relatively low, the lithium battery range extending system controls the fuel battery system to charge the lithium battery; when the load is relatively high, the lithium battery range extending system controls the fuel cell system and the super capacitor energy storage system to supply power to the load; when the fuel cell system runs out of energy, the lithium battery supplies power to the load. According to the scheme, the requirement for the large transient power limit needed by the system can be met, and efficient operation and long-distance cruising ability of the vehicle are ensured.
