Unmanned aerial vehicles (UAVs) have been applied to not only military missions like surveillanceand reconnaissance but also commercial missions like meteorological observation, aerial photograph, communicationrelay, internet network build and disaster observation. Fuel cells make UAVs eco-friendly by using hydrogen. Protonexchange membrane fuel cells (PEMFCs) show low operation temperature, high efficiency, low noise and highenergy density and those characterisitcs are well fitted with UAVs. Thus Fuel cell based UAVs have been activelydeveloped in the world. Recently, fuel cell UAVs have started to develope for high altitude UAVs because targetaltitude of UAVs is expanded upto stratosphere altitude. Long endurance of UAVs is essential to improve effectsof the missions. Improvement of UAV endurance time could be fulfilled by developing a hydrogen fuel storagesystem with high energy density and reducing the weight of UAVs. In this paper, research trend and analysisof fuel cell UAVs are introduced in terms of their altitude and endurance time and then the prospect of fuel cellUAVs are shown.
