Toshiba Develops World's Smallest Fuel Cells
An anonymous reader writes "When you think of Toshiba, you might think of notebooks, but fuel cells? Never. Well, at least not until up to now. Toshiba claims to have made the world's smallest fuel cell to date. The direct methanol fuel cell can fit inside of the smallest of gadgets, ranging from MP3 Players to portal DVD Players. Most fuel cells require a pump that can mix the methanol and water, and a fan to help cool the pump. This makes installing fuel cells in smaller items out of the question. However, Toshiba's new fuel cell does not require a fan or a pump to operate, which means it's much smaller in size, and can be installed in almost any small device."
One would think that the lack of a pump and fan would improve the effeciency, as well.
If the items are so small then how much energy can they realistically generate? Sure, I may get an extra five hours of my iPod, but if I have to go though the trouble of refilling the damn thing instead of just plugging it in, then I don't see the point.
I like portable fuel cells for laptop use because you can get about 18 hours out of one cell, which is great for flights to India, but when else do you really need that much battery life?

What, you think normal chemical batteries are safe? Between the highly caustic acids or alkalines, the heavy metals, lack of short circuit detection, propensity for exploding or shooting flames when overcharged, ordianary batteries are death machines if that's your way of thinking.
I don't worry about it much.

When I think of Toshiba, I think of plastics, bulk chemicals, PLC's, motors, instrumentation, batteries, X-ray machines, and I'm not sure that they still do this, but they used to even be into heavy machinery . . . as well as computers, semiconductors and consumer electronics. Are fuel cells really a stretch?
Does the author of the topic really think that /. readers are that naive?

Actually no. Your cells have the world's smallest fuel cell. And they were first.
Every time a fuelcell announcement is posted to Slashdot (and elsewhere), there are immediately panicked replies about fires and explosions. Of course prudence requires caution with any new, unprecedented technology. But have you ever noticed an *actual* fire or explosion problem with *any* fuelcell, at least in the last 5 years?
