I have an emergency charger that works on 4 AAA cells. Does that count?

As far as I'm concerned, fuel cell refers to an alternative to conventional chemical batteries, that work by converting a fuel (usually ethanol) to electrical power. This means that to 'recharge' the cell, you just top it up, which is pretty much intantaneous.
These things are mostly still in development stages. Some have been demonstrated, but practically nothing available commercially yet. A big problem is going to be air travel ('cos you just can't take a flammable liquid like ethanol on a plane).
So if this is what the question is asking, I can almost certainly say you'll have to wait some time yet...

@ qwerty_uk:
In USAnian Marketingspeak, "fuel cell" is often used when referring to external (rechargeable) batteries for portable devices.
Why they would do that, is beyond me. "Big battery" seems so more expletive.

Does this mean your P910 is powered by a Fuel Cell?

I'd love to have a fuel cell powered phone. TOshiba are developiong one which is siad to have a battery life of a few weeks on a drop of fuel.

uhm, a "fuel cell" doesn't need fuel
it generates power with water. somehow.
you add alcohol and water, and you get power.
the current models have a battery life of around 12 hours, compared to 4 hours for normal pda batteries.
which is not that great.
YET!
but the technology sounds really interesting.
i wonder how manufacturers will handle "liquid damage" in the future.
often, when your device is broken, you send it in and they say "your fault, you got it wet". even if you didn't, or didn't know you did it.
anyways ... car adapter would probably be your best bet.
then there are those adapters, where you plug in a 9V battery on one end, and plug the other end into your pda, and you're charging.
(9V batteries are the ones with two things on top, sort of round buttony things.)

Well that sounds quite a lot like fuel to me.
Fuel cells don't exist in anything other than experimental form, they are not going into production anywhere as of yet and they will not power a phone for weeks on a drop of fuel, they aren't that good.
Go to
www.theregister.co.uk and search for fuel cell to get some good info on em.

@ mores:
You sorta got it backwards. Basically, a fuel cell is nothing more than another type of chemical battery; in its purest form it combines hydrogen and oxygen to water and in the process generates electricity and heat. Just about every battery, rechargeable or not, does this, albeit with different chemicals.
The difference with a fuel cell is that it is an "open" cycle: the generated water is expellled from the battery as steam and needs to be replenished as hydrogen and oxygen from an outside source. So you don't "recharge" a fuel cell by plugging it in a wall socket, you pour in hydrogen (the oxygen being conveniently supplied by the atmosphere).
(M)ethanol-based fuel cells use a catalytic reaction to generate hydrogen from alcohol (because alcohol can be stored more easily than cryogenic hydrogen, especially in a portable phone!)
