[The Chosun Ilbo, October 10 2007] Korean Scientists Build Fuel Cell-Powered UAV

A team of Korean researchers has developed an unmanned aerial vehicle, or drone, capable of flying more than 10 hours on one charge of its hydrogen fuel cell. That's a remarkable feat considering a U.S.-made drone that is powered by batteries can fly only 40 to 60 minutes. The researchers expect the hydrogen fuel cell used in the drone will also be used in digital cameras and robots.
