UAV power supply systems

A next-generation power supply system DRON1000 based on our own hydrogen-air fuel cells designed for UAV is an alternative to Li-Ion batteries, with a game-changing ability to store up to 10 times more energy at comparable weight and dimensions, drastically increasing flight time up to 4 and the scope of operations available for a UAV. This allows efficiently completing multiple tasks from video surveillance to delivery of payload.

These systems utilize state-of-the-art design solutions and materials ensuring the maximum possible specific energy density for the specified capacity.

Basic competitive advantages in comparison with classical solutions: noiselessness, absence of vibrations, operating and starting temperatures up to -40 ℃, long service life, ecological compatibility, and high energy density of hydrogen-air fuel cells.
