Boeing fuel cells up in the air

Fuel cells seem to be everywhere from Suzuki motorcycles to the Honda FCX Clarity and now Boeing has them literally taking off. Of course, it's not the first time a fuel cell has been off the ground but it may well be the first time it has been the source of the motive force.
Using a two-seat Dimona motor-glider as the test vehicle with a "Proton Exchange Membrane (PEM) fuel cell/lithium-ion battery hybrid system to power an electric motor coupled to a conventional propeller" (pause for air) the pilot brought the plane up to an altitude of 3,300 feet, cut off the power from the batteries and flew solely on power from the fuel cell for 20 minutes at 62 mph.
Don't expect to seeing this technology powering a commercial airliner any time soon though. Boeing says that they don't "envision that fuel cells will ever provide primary power for large passenger airplanes" though it could be used for secondary systems and such. Check out all the details in their press release after the jump.
Press Release:
Boeing [NYSE: BA] announced today that it has, for the first time in aviation history, flown a manned airplane powered by hydrogen fuel cells.
MADRID, Spain, April 03, 2008
The recent milestone is the work of an engineering team at Boeing Research & Technology Europe (BR&TE) in Madrid, with assistance from industry partners in Austria, France, Germany, Spain, the United Kingdom and the United States.
"Boeing is actively working to develop new technologies for environmentally progressive aerospace products," said Francisco Escarti, BR&TE's managing director. "We are proud of our pioneering work during the past five years on the Fuel Cell Demonstrator Airplane project. It is a tangible example of how we are exploring future leaps in environmental performance, as well as a credit to the talents and innovative spirit of our team."
A fuel cell is an electrochemical device that converts hydrogen directly into electricity and heat with none of the products of combustion such as carbon dioxide. Other than heat, water is its only exhaust.
A two-seat Dimona motor-glider with a 16.3 meter (53.5 foot) wingspan was used as the airframe. Built by Diamond Aircraft Industries of Austria, it was modified by BR&TE to include a Proton Exchange Membrane (PEM) fuel cell/lithium-ion battery hybrid system to power an electric motor coupled to a conventional propeller.
Three test flights took place in February and March at the airfield in Ocaña, south of Madrid, operated by the Spanish company SENASA.
During the flights, the pilot of the experimental airplane climbed to an altitude of 1,000 meters (3,300 feet) above sea level using a combination of battery power and power generated by hydrogen fuel cells. Then, after reaching the cruise altitude and disconnecting the batteries, the pilot flew straight and level at a cruising speed of 100 kilometers per hour (62 miles per hour) for approximately 20 minutes on power solely generated by the fuel cells.
According to Boeing researchers, PEM fuel cell technology potentially could power small manned and unmanned air vehicles. Over the longer term, solid oxide fuel cells could be applied to secondary power-generating systems, such as auxiliary power units for large commercial airplanes. Boeing does not envision that fuel cells will ever provide primary power for large passenger airplanes, but the company will continue to investigate their potential, as well as other sustainable alternative fuel and energy sources that improve environmental performance.
BR&TE, part of the Boeing Phantom Works advanced R&D unit, has worked closely with Boeing Commercial Airplanes and a network of partners since 2003 to design, assemble and fly the experimental craft.
The group of companies, universities and institutions participating in this project includes:
- Austria -- Diamond Aircraft Industries
- France -- SAFT France
- Germany -- Gore and MT Propeller
- Spain -- Adventia, Aerlyper, Air Liquide Spain, Indra, Ingeniería de Instrumentación y Control (IIC), Inventia, SENASA, Swagelok, Técnicas Aeronauticas de Madrid (TAM), Tecnobit, Universidad Politécnica de Madrid, and the Regional Government of Madrid
- United Kingdom -- Intelligent Energy
- United States -- UQM Technologies

I wonder how far the plane would have flown if all the hydrogen fuel cell components were replaced by batteries?

Finally, a use for fuel cells that actually makes sense -- aircraft, where you don't care about volume so much as weight. I'm still struck by the the ridiculous "fuel cell forklifts" notion.

@Eletruk
Don't know, but I do know without the batteries, this plane probably wouldn't even fly because fuel cells still have horribly low power output. Otherwise, they wouldn't even need batteries on this plane (or even other fuel cell vehicles).
But KarenRei's right, the weight will be lower using hydrogen compared to just batteries.

Aviation is one of the very few applications where the very high energy per unit weight advantage of hydrogen could override all of the significant disadvantages of hydrogen.
It may be worthwnile to use a fuel cell to provide the electricity needed by commercial aircraft, as it is more efficient than gas turbine power. The higher cost of fuel cells could be amortized with fuel savings in a reasonable period, especially on heavily used aircraft. Solid oxide fuel cells could run on H2, or on more easily stored and readily available jet fuel.

That would all be great, except France already flew an all electric plane for twice as long entirely on batteries:

So once again, Hydrogen proves to be less capable.

These "fly" on hydrogen.

Another Egglectric theory that's "disposable."

Leave it up to beoing to come up with something like this . It would be crazy if lithium ion batteries get so advanced that you could fly a fully loaded 787 3000 miles and then use hydrogen as a back up for added range. Imagine having to charge an airplane using high voltage and ultra state compactors to achieve average speed of 20 minutes . Now wouldn't that be something. :)

"the pilot brought the plane up to an altitude of 3,300 feet, cut off the power from the batteries and flew solely on power from the fuel cell for 20 minutes at 62 mph."
This is testimony to the poor power output of fuel cells. (Many fuel cell vehicles use a battery for boost) Maybe once oil is too expensive for commercial aircrafts, they will use something similar to Boeing's setup: a powerful battery for takeoff and a more energy-dense hydrogen tank to fuel the lower-power fuel cell.
Wait a mintue....wouldn't they just use biofuels instead of a heavier, more expensive fuel cell/battery set up?

Russia has built liquid hydrogen power planes.
I think fuel cells would make a good replacement for a APU.
What i would love to try to build a sterling engine powered UAV with a massive wing span.

at take off a 777-300ER consumes 165,000,000 watts of energy a 787 around 60 million watts of power. So i dont think we will see electric commercial planes just yet

I don't think people understand that each of the engines on a commercial aircraft can power a medium-sized town. Until you see fuel cells in the tens of Megawatts, then it will not provide flight power for aircraft.
