Hydrogen Fuel Cells On the Way!!

It wont be long now!!! This is from an article on Lycos news today.
http://ise.fhg.de/
To power more energy-hungry laptops or Camcorders, Fraunhofer built hydrogen-powered fuel cell systems that fit right into the battery slot of the devices. Fuel cells convert hydrogen and oxygen into energy, where the only byproduct is water. For example, the Sony camcorder is powered by a miniature fuel cell with a performance capability of 10 watts at 8 volts, Hebling said.

Hydrogen is stored in a little cigar-shaped metal container, which holds about 20 to 30 liters of hydrogen.

"This is enough to power a 30-watt laptop computer for about one to two hours," Hebling said.

A larger container at the bottom of a laptop computer could hold much more hydrogen, enough to be sufficient for more than 10 hours of operating time, according to Hebling. The container is filled with a metallic powder ("Nano powder"), whose consistency is like meal. Hydrogen is absorbed by the surface of the powder.

But are these fuel cells economically viable?

"In mass production, fuel cells are already competitive with rechargeable lithium-ion batteries, because they are also high-price technologies," Hebling said. He estimates that metal-hydride containers will be available for about $30 –- much cheaper than the $200 for rechargeable batteries. "What’s missing is a clever distribution method for hydrogen. Why not sell or replace it like soda (dispensers) at gas stations?"

Laptops are kids stuff !

If you were able to go down to our (Adam Opel AG) engineering workshops this afternoon you would see a very nice fuel cell powered Opel Zafira 7-Seat Minivan called 'HydroGen1'.

It just came back from breaking 15 international records at the General Motors Proving Ground in Mesa AZ including 1000 km at an average of 90 kmh.

You betcha, fuel cells are on the way in !

So, if the by product is water, does that mean you get a wet lap when using your laptop?

Or does it just steam gently? Could prove unsettling for your fellow travellers in an airplane!

dave:
airline regs don't allow compressed gases to be carried aboard. Have to load the cells as cargo. You ought to look at the full list of restriced articles eg mercury thermometers, christmas crackers, aerosols, nail varish remover, magnetic materials etc

If they only new the fire or explosive potential of laptop Cells I am sure they would not let you carry laptops and cell phones.
As far as the water goes, the article said there was an evaporator. I suppose thats one word to describe your 1 GHz processor .
Fuel cell powered cars is very cool, but so is the light weight prospect of flying RC!

Can we utilize the hydrogen to also fill the wing for bouyancy to have a near weightless airplane?

Hey, you could iron your trousers while you use it!

That is just not true. I actually run into a guy from time to time who works on fuel cells for cars and he readily admits that they are not economically feasible at all now. And there are hydrogen fuel stations already around in California but still without vast grants or prototype projects the power systems are exhorbitantly expensive. It's not just the infrastructure that isn't the reason it's ubiquitous, whether we talk cars or small devices.

Fuel cells continue to not be a mass produced tech because they are very, very expensive.

I work in the fuel cell industry and it will be a long time before there is consumer products at a reasoneable price and easy to use. The 99% pure hydrogen used for fuel cell is neither cheap or easy to get in small quantity

Fuel cells are cool... I know because I own one (check my blog). But the problem is getting the fuel. Currently, to separate H20 requires so much fuel, it'd be easier to just to run a car on that. Or at least is my limited understanding. I just play with my fuel cell, and know its cost a lot to get more fuel.. lol.

Is anybody aware they are replying to a 7 year old thread? Technology has changed quite a bit, especially for lipos in that time period.
