Europe gets taste for power in new unmanned future
Europe’s first hydrogen-powered UAS was unveiled on 15 November at London’s Commercial UAV Show, demonstrating how extended flying times could become a reality for smaller platforms.
The e-Drone and fuel cell technology was developed by Estonian-based company Skycorp and UK-based Intelligent Energy respectively, in response to a request by a customer for a small UAS with increased flying time.
Hydrogen fuel cells were selected as these are able to extend flight times over three times that of the more widely used Lithium-ion polymer batteries, due to the higher energy to mass ratio.
These cells also require less downtime due quick
