Horizon Fuel Cell has issued a press release about the successful maiden flight (YouTube video) of a zero emission UAV prototype powered by hydrogen. The fuel cell powered flying robot, called the HyFish was designed by Germany's Deutsches Zentrum fuer Luft-und Raumfahrt (DLR - aka the German Air & Space Center). A special fuel cell was developed for the UAV, providing 1.3kW of power from an 800g cell. The result is a new power density record of 1.5W/gm. The fuel cell system is expect to allow flight times of 15 to 30 hours. The zero emission aspect is also helpful in that it may reduce the amount of greenhouse gas resulting from aviation, which now accounts for up to 9% of the total. The HyFish UAV will be on display to the general public at the Hannover Fair April 16 to 20, Stand G 32/1, Hall 13. More info, including an x-ray image of the UAV can be found on the DLR HyFish news release (German language). An older 3D structural rendering is also available.
