The invention discloses a multi-rotor unmanned aerial vehicle with a modularized cathode open type air-cooled fuel cell stack power system. The cathode open type air cooling fuel cell power system multi-rotor unmanned aerial vehicle comprises a hydrogen storage system, a fuel cell system, a storage battery system, an intelligent control system, a power system and a supporting system. Optimal integration of a system control strategy, a power mass ratio and key parts of the unmanned aerial vehicle is realized, and the unmanned aerial vehicle can be realized by assembling a plurality of module fuel cell power systems according to different load types and power endurance requirements. Besides, the fuel cell system is of an annular structure and is coaxially connected with the rotors through turbulent flow supporting columns, surrounding air can be absorbed into the fuel cell through rotation of a bottom fan or a top multi-rotor power fan of the fuel cell to react and generate electricity, the air flow speed in an annular channel of the fuel cell can be increased, and the power generation efficiency is improved. The heat dissipation effect of the fuel cell stack, the power generation efficiency of the system and the cruising ability of the unmanned aerial vehicle are improved.
