The invention provides a fuel cell stack hydrogen circulation system for an unmanned aerial vehicle and a control method of the fuel cell stack hydrogen circulation system. The two end faces of the compression cavity are open, one end face forms the input end of the compression cavity, and the other end face forms the output end of the compression cavity; the water outlet in the compression cavity is arranged close to the one-way double-layer air inlet device; when water in the compression cavity flows out through the water outlet, the push rod does not make contact with the one-way double-layer air inlet device. The push rod extends into the compression cavity through the input end of the compression cavity and is attached to the inner wall of the compression cavity; a one-way double-layer air inlet device; after water in the compression cavity flows into the drainage device, the one-way double-layer gas inlet device is opened under the thrust action of the push rod, so that compressed hydrogen enters the transition pressurization gas storage bottle; the output end of the transition pressurizing gas storage bottle is sequentially connected with the one-way gas inlet valve, the three-way valve and the gas inlet of the fuel cell stack; and a hydrogen source. The device integrates the functions of hydrogen circulation, hydrogen pressurization and hydrogen humidification.
本发明提出了一种无人机用燃料电池堆氢气循环系统及其控制方法,该系统包括:燃料电池堆;压缩腔,其两端面均敞开,其一端面形成压缩腔的输入端,另一端面形成压缩腔的输出端;压缩腔上的排水口,靠近单向双层进气装置设置;当压缩腔内的水经排水口流出时,推杆与单向双层进气装置之间不接触;推杆,其通过压缩腔的输入端伸入压缩腔内,与压缩腔的内壁贴合;单向双层进气装置;当压缩腔内的水流入排水装置后,单向双层进气装置在推杆的推力作用下打开,以供压缩的氢气进入过渡增压储气瓶;过渡增压储气瓶,其输出端依次连接单向进气阀、三通阀和燃料电池堆的进气口;及氢气源。本发明集成了氢气循环、氢气增压和氢气加湿的功能。
