World's Smallest Fuel Cell

casio-fuelcell.jpg

Casio Computer Co has announced that it has developed the world's smallest fuel cell.

Large-scale polymer electrolyte fuel cells (PEFC) are already in development for use in automobiles. What Casio has succeeded in doing is to miniaturize a PEFC so that it is similar in size to a conventional lithium-ion battery.

However, the PEFC battery has a capacity nearly four times that of a lithium-ion battery. Laptop computers should be able to run on PEFC power for 8-16 hours.

Casio hopes to introduce its fuel cell to the market after regulators are expected to allow PEFCs on the market, around 2007.

Is it re-usable? Re-fillable?

Yes, I (and probably everyone else) have the same question. Is this refillable? Disposable (if so, LOOK OUT LANDFILLS)? What's it run on?

I won't ask for price only because it's too soon, and because it's not really relevant. The marketplace will determine that.

Well, I looked elsewhere and got what looks like an answer. It does look like it's supposed to be refilled, and apparently the refilling process is kind of awkward.

Not exactly goof-proof. Still, things do seem to be going in a positive direction. The above quote from http://neasia.nikkeibp.com/wcs/leaf?CID=onair/asabt/news/306294
