In this paper, the performance of the proton exchange membrane fuel cell (PEMFC) for cruising hybrid powered fixed-wing unmanned aerial vehicle (UAV) is investigated in different temperatures. The hybrid powered UAV has two power sources: FC and battery. In this regard, Lithium-Ion (Li-ion) and Nickel Metal Hydride (Ni-MH) are selected as battery types. The PEMFC performance is analysed in three scenarios determined as FC, FC & Li-ion and FC & Ni-MH. The linearized UAV model is simulated in MATLAB/Simulink and only cruise phase of flight considered. Simulation results shown that the UAV model with pure FC has the longest endurance. The endurance has influenced from total weight of the UAV and hybrid system characterization. Furthermore, temperature changes also affect fuel consumption. This paper provides a general description of the proposed UAV model with three types of hybrid power source and describes the design methods and simulation cases for long endurance.

本文研究了质子交换膜燃料电池（PEMFC）在不同温度下巡航混合动力固定翼无人飞行器（UAV）的性能。混合动力无人机有两种电源：FC和电池。在这方面，锂离子（Li-ion）和镍氢金属（Ni-MH）被选作电池类型。在确定为FC，FC和锂离子以及FC和镍氢的三种情况下分析了PEMFC的性能。在MATLAB / Simulink中模拟了线性化的无人机模型，并且仅考虑了飞行巡航阶段。仿真结果表明，纯FC无人机模型具有最长的耐久性。耐久性受无人机总重量和混合动力系统特性的影响。此外，温度变化也会影响燃油消耗。
