Drone Flies for 4 Hours using Hydrogen Fuel Cell http://www.roboticstrends.com/article/hycopter_drone_flies_for_4_hours_via_hydrogen_power
[deleted] on May 21, 2015 6:14 pm Could probably have flown longer if it used a [direct-methanol fuel cell](https://en.wikipedia.org/wiki/Direct_methanol_fuel_cell). Hydrogen is hard to store compactly.
