700Wh/kg Fuel Cell for Drones

April 26, 2015 by Jeff Shepard

Horizon Energy Systems Pte Ltd. (HES) claimed a breakthrough on-demand hydrogen generation technology based on a solid fuel system, further improving the flight endurance of small fuel cell electric drones. The unique ability to perform long endurance missions with a low-altitude mini-UAV provides considerable new benefits in border patrol, infrastructure surveillance, exploration, critical asset and environmental monitoring.

“The new AEROPAK-S is the result of years of effort in simplifying what are typically complex systems and making them easy to deploy,” said Taras Wankewycz, HES’ Chief Executive Officer. “We have explored a number of feedstock options through the years and our new system trumps them all on performance, safety and scalability in manufacturing.”

The new 700Wh/kg solid fuel AEROPAK-S completely eliminates the need for a complex catalytic reactor, which reduces size, weight and complexity, while offering a self-contained, plug and play fuel cartridge system. AEROPAK-S has already powered a commercial mini-UAV flight earlier this year.

Custom versions of the system have been in stealth development with several leading aerospace OEMs, some of which are moving to serial production in the coming months. While the company’s visibility has mostly been in the fixed-wing segment, it expects to set a new world flight duration record in the multi-rotor segment in the coming weeks.
