In this episode, the Roswell Flight Test Crew hears from Julian Hughes, the senior vice president for Intelligent Energy. He describes how the company has developed a small, lightweight hydrogen fuel cell that can be mounted in place of a conventional lithium-polymer battery on board a drone to radically extend its flight time. Fuel cells are three times more energy-dense than a conventional drone battery. In the example of a DJI Matrice 100, on display at the Intelligent Energy booth at InterDrone, flight time increases from 20 minutes to 90 minutes. Also, time to re-charge is also dramatically reduced. Once the hydrogen gas on board the drone is exhausted, the pressure cylinder can be re-filled in as little as two minutes, or replaced with an another, full cylinder. Hydrogen gas is widely available from industrial gas suppliers.
