Fuel cell aircraft

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 plane

04 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 Tiger 

The 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 Antar​es DLR-H2

The 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.

Fuel cell for model planes

Horizon Fuel Cell Technologies latest hydrogen fuel cell release is designed as a drop-in replacement for battery packs used in small electric Unmanned Aerial Systems (UAS). Weighing 4.4lbs (2kg) and storing 900Wh of usable electric energy, the Aeropak can to increase flight endurance by up to 300% over lithium batteries, meaning longer range missions and more energy to run on-board cameras and sensors.
