The invention discloses a long-endurance hydrogen fuel cell unmanned aerial vehicle, and belongs to the technical field of unmanned aerial vehicles, the long-endurance hydrogen fuel cell unmanned aerial vehicle comprises a rack, a spiral assembly and a control assembly, the rack comprises an upper supporting plate, a lower supporting plate and a supporting column, the upper supporting plate and the lower supporting plate are each provided with a plurality of mounting holes, and the supporting column is arranged between the upper supporting plate and the lower supporting plate and used for fixing the upper supporting plate and the lower supporting plate; the spiral assemblies are connected with the rack and arranged between the upper supporting plate and the lower supporting plate, and the multiple sets of spiral assemblies are arranged around the rack at equal angles and used for driving the rack to ascend. The control assembly is connected with the rack, the control assembly is electrically connected with the spiral assemblies at the same time, and the control assembly comprises a hydrogen storage bottle detachably connected with the upper supporting plate. The long-endurance hydrogen fuel cell unmanned aerial vehicle solves the problems that in the prior art, the weight is large, the wind resistance is large, the energy consumption is high, the cruising ability is low, and the requirement that the unmanned aerial vehicle executes more tasks in the air cannot be met. The invention has obvious effect and is suitable for wide popularization.
