The invention discloses an unmanned aerial vehicle hydrogen supply system, which comprises a hydrogen cylinder for providing a hydrogen source for a hydrogen fuel cell stack; the hydrogen supply pipeline is arranged between the hydrogen cylinder and the hydrogen fuel cell stack; the pressure reducing system comprises a first-stage pressure reducing valve and second-stage pressure reducing valves, and the first-stage pressure reducing valve is communicated with the second-stage pressure reducing valves at the same time; a stop valve is arranged between the hydrogen cylinder and the first-stage pressure reducing valve, and outlets of the plurality of second-stage pressure reducing valves are respectively and correspondingly communicated to the plurality of hydrogen fuel cell stacks. High-pressure hydrogen is shunted and output through multiple paths of second-stage pressure reducing valves, stable hydrogen can be output for the hydrogen fuel cell stack, stable work of the electric pile is guaranteed, the electric pile system of the whole unmanned aerial vehicle is formed by connecting a plurality of small electric piles in series, the electric pile system can avoid a water cooling system, meanwhile, the space can be reduced, the weight can be reduced, and the cost is reduced. The flight requirements of the unmanned aerial vehicle are met.

    本发明公开了一种无人机供氢系统,其包括:氢气瓶,为氢燃料电池堆提供氢气来源;供氢管路,布置于所述氢气瓶和氢燃料电池堆之间;减压系统,包括第一级减压阀和第二级减压阀,第一级减压阀同时与若干第二级减压阀连通;所述氢气瓶与所述第一级减压阀间布置有截止阀,若干第二级减压阀的出口分别对应连通至若干氢燃料电池堆。本发明将高压氢气通过多路第二级减压阀分流输出,可以为氢燃料电池堆输出稳定的氢气,保障了电堆的稳定工作,整个无人机的电堆系统是由若干个小电堆串联组成的,可以使电堆系统避开水冷系统,同时可以减小空间及减轻重量,满足无人机的飞行需求。
