The invention provides a novel high-hydrogen-storage aerial hydrogenation unmanned aerial vehicle. Hydrogen is generated through devices such as a metal hydrogen storage reactor, and membrane materials are arranged on the surfaces of the wings, so that water generated by the fuel cells can be further converted into hydrogen for recycling; a hydrogenation beam composed of two rigid telescopic pipes below the tail can supplement hydrogen energy for the unmanned aerial vehicle; a metal hydrogen storage material and a heat exchange fluid channel are arranged in the hydrogen storage reactor; the liquid hydrogen storage tank adopts a double-layer vacuum heat insulation container to ensure good heat insulation; a pressure sensor is installed in the air bag type buffer tank and used for detecting the pressure of hydrogen, and the inlet and outlet amount of hydrogen is controlled in time through a negative feedback mechanism. In addition, water generated when the hydrogen fuel cell works can be subjected to photolysis through the water storage device coated with the membrane material, wherein generated hydrogen enters the buffer tank to be recycled again. The invention can solve the problem that hydrogen is insufficient in the flight process of an existing unmanned aerial vehicle, wherein the energy can be supplied to the hydrogen energy unmanned aerial vehicle in work in time, and therefore the long endurance performance of the hydrogen receiving vehicle is improved.
