ScanEagle Flies with Fuel Cell Power

Ballard Power Systems announced that the company’s subsidiary, Protonex, has successfully powered test flights of the ScanEagle unmanned aerial vehicle (UAV) with the Company’s PEM (proton exchange membrane) fuel cell propulsion system.

“These test flights have successfully demonstrated the integration and operation of our fuel cell propulsion system as well as the high pressure hydrogen fuel tank,” said Paul Osenar, President of Protonex.
“The tests also documented acoustic footprint reduction that will enable mission routes that take the ScanEagle closer to its targets. In addition, test flights confirm that our fuel cell propulsion system offers power during flight that can be used to support greater payload diversity. When combined with improved reliability and other advantages over internal combustion systems, fuel cells are proving to be a tremendous fit for UAVs.”
Advantages of the Protonex fuel cell propulsion modules over traditional internal combustion engine propulsion systems include: significant improvement in the expected MTBF (mean time between failures) of up to 5x; silent operation; 100% throttle flexibility, including mid-air start-stop capability; and use of existing JP8 fuel in ground refuelling systems.

Peter Kunz, Insitu’s Chief Technology Officer noted, “Insitu continues to progress toward our goal of offering all-electric power and propulsion system options for Insitu platforms. Now in developmental testing, the Protonex fuel cell system has exceeded our power requirements and has integrated very well with the initial target aircraft systems and with general unmanned aerial system, or UAS, operations. Additional performance tests and customer demonstrations are planned throughout the remainder of this year.”
