Extending flight autonomy without compromising performance is a critical challenge in UAV system development. Previous. . The interest in electric unmanned aerial vehicles (UAVs) is rapidly growing in recent years. The reason is that UAVs have abilities to perform some di cult or dangerous tasks, with high mobility, safety, and low cost. It should be noted that UAVs are revolutionizing many public ser-vices including. . Electric vertical take-off and landing (eVTOL) aircraft have gained considerable interest for their potential to transform public services and meet environmental objectives. Designing an effective power supply for eVTOL is challenging due to the extreme power requirements during takeoff and. . In this paper, a novel fully-active PEMFC-Lithium battery hybrid power system is designed for UAV applications. The proposed construction employs an automatic ON/OFF switch in parallel with a DC-DC converter to control the PEMFC and a second automatic ON/OFF switch replacing the commonly used DC-DC.
