- Fuel cell powered electric UAV low altitude high endurance flight missions.
- Off-the-shelf fuel cell technology and chemical hydrides based generator.
- Challenges encountered in demanding weather conditions for the generator operation.
Boeing Research & Technology Europe has designed, developed and subsequently bench and flight tested, in a wide range of different operative conditions, an electric Unmanned Air Vehicle (UAV) powered by a hybrid energy source. The energy source features a 200Â We Polymer Electrolyte Membrane (PEM) fuel cell system fed by a chemical hydride hydrogen generator that produces highly pure hydrogen at the fuel cell operating pressure from the controlled hydrolysis of Sodium Borohydride (NaBH4), resulting in 900Â Wh of energy from 1Â L of chemical solution. Equipped also with high specific energy Lithium Polymer batteries, this fuel cell powered UAV is able to achieve flight durations close to 4Â h.This paper summarizes the aircraft and systems design, the results of the bench and flight tests along with the main challenges faced during this development and the lessons learned for future optimization.
