Active Current Sharing and Source Management Methods on Fuel Cell/Battery Hybrid System for Drones With High Power Density

This paper proposes the fuel cell/battery hybrid structure and the power distribution method considering hybrid system suitable for fuel cell/battery hybrid drones. The proposed structure can operate at high power through 5-types of fuel cell and battery distribution control methods. System structure and control methods are verified through power distribution control experiments by distinguishing mode for the operation required for drone driving based on the hardware of the 5kW drone with fuel cell stacks.
