Unmanned aerial vehicles (UAVs) powered by electric motors are in an advantageous position because of their properties, such as low noise and thermal footprint, high efficiency, and zero emissions. Lithium‐based batteries have restrictive factors for flight duration due to its low energy density, difficult, and expensive charging methods. It is aimed to extend flight duration of a battery powered mini‐type UAV with a combined system, which includes a 200 W polymer electrolyte membrane (PEM) fuel cell, a hydrogen generation system based on in situ hydrolysis of sodium borohydride, a hybrid power management system consisting of fuel cell and battery, and an embedded control system. It is observed that a fuel cell‐based energy system is able to extend endurance by twofolds compared with an only battery powered system. This is the first study in the literature that investigates the flight duration of UAVs in battery versus fuel cell according to actual flight data.

燃料电池驱动的微型无人机的集成过程控制-电源管理系统设计和飞行性能测试

由电动马达驱动的无人机（UAV）由于其特性（例如低噪音和热足迹，高效率和零排放）而处于有利位置。锂基电池由于能量密度低，充电方法困难且价格昂贵而对飞行时间有限制。它旨在通过组合系统来延长电池供电的微型无人机的飞行时间，该系统包括一个200 W聚合物电解质膜（PEM）燃料电池，一种基于氢硼化钠原位水解的氢生成系统，一种混合​​动力系统。由燃料电池和电池组成的管理系统，以及嵌入式控制系统。可以观察到，与仅电池供电的系统相比，基于燃料电池的能源系统能够将耐久性提高两倍。
