Problems solved by technology
For example, multi-rotor UAVs powered by lithium batteries generally have a flight time of less than half an hour, so they cannot fly beyond visual range effectively, and it is especially difficult to overcome complex terrain such as mountains and waters, so they cannot complete professional and complex flight tasks

Embodiment Construction
[0019] refer to figure 1 , the multi-rotor fuel cell UAV may include a fuel cell system 1, a frame 2, a flight lifting component 3, a control mechanism 4, and the like.
[0020] The frame 2 includes a plurality of, for example, four arms 30 protruding outwards along it, and these arms 30 are arranged at approximately equal intervals around the frame 2 to ensure the flight stability of the UAV. Each boom is composed of a first boom element 31 and a second boom element 33 . A folder is provided at the root of the first arm element 31 away from the frame 2 to be connected with the second arm element 33 .
[0021] However, it can be understood that the connection between the first arm element and the second arm element is not limited to the folder, but can be any known way to achieve a stable connection between the two, such as hinged, screwed, etc.
[0022] At the end of each arm 30 a corresponding flying lift member 3 is provided. Each flight lifting member 3 may for example ...

The invention relates to an unmanned aerial vehicle with fuel cells. The unmanned aerial vehicle comprises a fuel cell system, a framework, flying and lifting components and control mechanisms. Power can be provided for the unmanned aerial vehicle with the fuel cells by the fuel cell system, so that propellers of the flying and lifting components can rotate by the aid of the control mechanisms, the unmanned aerial vehicle can fly; the fuel cell system is arranged below the propellers, so that the air quantity required to allow the unmanned aerial vehicle to fly can be provided for the fuel cell system by the propellers, and heat can be dissipated for the fuel cell system by wind power generated by the propellers. The invention further relates to a method for controlling the unmanned aerial vehicle with the fuel cells. The unmanned aerial vehicle with the fuel cells and the method have the advantages that required air flow and pressures can be supplied to the fuel cells by the wind power generated by the propellers of the unmanned aerial vehicle, the unmanned aerial vehicle can have a function of sufficiently dissipating the heat for the fuel cell system, and accordingly the fuel cells can reliably run in allowable temperature ranges.
Description
technical field [0001] The invention relates to the field of fuel cell unmanned aerial vehicles, in particular to a fuel cell unmanned aerial vehicle with simple structure, light weight, multi-rotors and long driving range. Background technique [0002] Unmanned Aerial Vehicle (UAV) is an unmanned aircraft controlled by radio remote control equipment and its own program control device. UAV is actually a general term for unmanned aerial vehicles. From a technical point of view, it can be divided into: unmanned helicopters, unmanned fixed-wing aircraft, unmanned multi-rotor aircraft, unmanned airships, and unmanned paraplanes. The characteristic of UAV is that there is no cockpit on board, but it is equipped with autopilot, program control device and other equipment. The personnel on the ground, on the ship, or at the remote control station of the parent aircraft track, locate, remotely control, telemeter and digitally transmit it through radar and other equipment. [0003] ...
