The most powerful fuel cell system integrated in Hy4 aircraft

The fuel-cell hybrid-electric power generation system was significantly improved to make the Hy4 drive system more efficient and reliable. The fuel-cell system, with the Power Management, Control, and Delivery (PMCD) module, was integrated on board the Hy4 aircraft. The battery system’s physical properties were sized to optimally fit into the fuel cell system’s framework.

The hydrogen fuel system is now completed and ready for ground testing. The system integrated into the Hy4 aircraft, capable of continuous power output of 52 kW and peak power of 120 kW, will be the most powerful fuel-cell system ever used to power a flying aircraft.
