| A fuel cell is a device that transforms the energy of hydrogen into electricity by combining the hydrogen with oxygen in a “cold” combustion. The only exhaust products are water, heat and oxygen-depleted air. | The fuel cell will provide the entire power for the cruise but the system will draw on the help of lightweight Li ion batteries during take-off and climb, the segment of flight that requires the most energy. |

Fuel cell powered plane04 04 2008 In an aviation first, Boeing announced that it has successfully flown a manned airplane powered by hydrogen fuel cells. The tests took place in February and March at an airfield south of Madrid. The plane, a two-seat Dimona motor-glider, was modified by Boeing to include a proton Proton Exchange Membrane (PEM) fuel cell/lithium-ion battery hybrid system to power an electric motor coupled to a conventional propeller. |

2009 USA Navy - Ion TigerThe U.S. Navy has developed a hydrogen-powered aircraft that can fly for nearly an entire day without refueling. During a test flight the Ion Tiger, an unmanned air vehicle (UAV), stayed airborne for approximately 23 hours and 17 minutes. The electric fuel cell propulsion system onboard the aircraft features a 550-Watt (0.75 horsepower) fuel cell that researchers say is 4 times more efficient than a comparable internal combustion engine. The Ion Tiger weighs approximately 37 pounds and carries a 4- to 5-pound payload. |

2009 Antares DLR-H2The Antares DLR-H2 is powered by fuel cells and was commissioned by the German Aerospace Centre (DLR) with the goal of developing fuel cells for a reliable on-board power supply for wide-body airliners. The world's first piloted aircraft capable of taking to the air using only power from fuel cells took off in Germany July 2009. Read more at: http://phys.org/news166191289.html#jCp |
