Hydrogen fuel cell propulsion for UAVs

research and development

Military defense and naval operations

Electrochemical devices that convert hydrogen and oxygen into electricity to power electric motors in aircraft.

Hydrogen stored in a liquid state, which requires cryogenic temperatures. It was used in the Ion Tiger UAV for extended flight.

United States

An effort by the U.S. Naval Research Laboratory to extend the flight endurance of the hydrogen-powered Ion Tiger unmanned aerial vehicle (UAV).

A hydrogen-powered unmanned aerial vehicle (UAV) equipped with a fuel cell propulsion system that uses liquid hydrogen fuel. It has set endurance records for UAV flight.
