The craft, which has a wingspan of 22 feet, has made several flights lasting up to a minute. Fuel cell UAVs could offer some distinct advantages. One, they are quiet, which, considering that UAVs are used for battlefield reconnaissance, is important. Two, they leave a more faint heat signature than UAVs on electric motors, so they potentially won't get picked up by counterintelligence systems as easily.
