A fuel cell powered unmanned air vehicle (UAV) named Kenyalang-1 was designed, built, and flight-tested at the Universiti Teknologi MARA (UiTM) in Shah Alam, Malaysia. The UAV is propeller-driven by a DC brushless motor, powered by a 500 W proton exchange membrane (PEM) hydrogen fuel cell. The objective was to demonstrate the design and technological challenges involved and determine the relative merits or shortcomings that fuel cell electrically-powered propulsion systems have over conventional systems. This paper describes the UAV design (airframe, propulsion, and avionics) and measured performance during initial flight tests. The results of this analysis will be used to improve the UAV and power plant system for future production models.
