The invention discloses a hydrogen fuel cell unmanned aerial vehicle with a liquid cooling heat dissipation structure. The hydrogen fuel cell unmanned aerial vehicle comprises an unmanned aerial vehicle body, a hydrogen fuel cell system, a heat dissipation vehicle arm with an inner cavity, a liquid distribution header pipe, a first water pump, a liquid guide downstream pipe, a liquid guide backflow pipe, a propeller, a flow uniformizing mechanism and a liquid collection header pipe. Cooling liquid absorbing heat is evenly distributed to each liquid distribution branch pipe through the liquid distribution header pipe and the flow uniformizing mechanism and then flows into the liquid guide downstream pipe and the liquid guide backflow pipe in the heat dissipation machine arm for heat dissipation, rotor wing wind of a propeller is fully utilized for heat convection heat dissipation, and then the cooling liquid is circulated into a hydrogen fuel cell system through the liquid collection header pipe. Water-cooling heat dissipation is adopted in the whole process, meanwhile, a water-cooling heat dissipation device is combined with the unmanned aerial vehicle frame, the vehicle arms of the unmanned aerial vehicle frame serve as heat dissipation devices, an additional heat dissipation device structure can be omitted, the weight can be reduced, rotor wing wind is fully utilized for heat convection, heat dissipation fan components can be omitted, the weight is reduced, and therefore the heat dissipation effect is guaranteed, and meanwhile the heat dissipation efficiency is improved. And the weight is reduced.
