A safe and efficient hydrogen fuel cell power device of a long-endurance unmanned aerial vehicle comprises a fuel cell stack, a hydrogen supply system, an air supply system, a hydrogen recovery system, a power recovery system and a fuel cell stack controller. According to the fuel cell electric bicycle power system, the system and components are integrally assembled, and a programmable logic controller is used for controlling gas (hydrogen and oxygen) supply of the whole fuel cell power system, hydrogen recovery and power output of the fuel cell power system. According to the invention, the water electrolysis module is used for shunting power, so that the hydrogen fuel cell always keeps stable output in a return landing section, a leveling section, a landing section and a skating section of the unmanned aerial vehicle, and water management imbalance caused by power fluctuation of the hydrogen fuel cell is avoided. The simple, safe and efficient hydrogen fuel cell power device for the long-endurance unmanned aerial vehicle effectively reduces the difficulty of water management, improves the safety of the unmanned aerial vehicle and prolongs the flight time of the unmanned aerial vehicle.
