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."

    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?

      Refilling the thing creates an instant recharge and may be done where there is no place to plug in, like on an 18 day walk, which may not be your thing, but is for plenty of others, who may well find GPS nice to have along under the same circumstances.

      Great for boaters too.

      Most of the world is not yet wired, and much of that even lacks availiblity of batteries. Nontheless people tend to crawl all over those places from time to time. Alcohol can even be made on site, even on a desert island in small quantities.

      I can understand that it may not fit your urbanized needs, and that's ok. Just understand that there are a billion or more whose needs it fits pretty well.

      The tiny fuel cell uses 2cc of concentrated methanol to provide 20 hours of power at 100 milliwatts, max.

      "Concentrated methanol"???

      Pure methanol perhaps, but I don't believe you can concentrate methanol at all.

      With regard to refilling. This will be done with a can of compressed methanol

      Errr.. another point of error: being a liquid at normal temperature, methanol is virtually incompressible.

      This process will be very similar to the way that butane cigarette lighters are refilled and have been for more than 30 years. Just for the record, butane is much more flamable/explosive than methanol

      No, there's another *huge* difference -- at normal temperature/pressures, butane is a gas so it can be compressed for storage and refil (even to the extent that it becomes a liquid). No such option is available with methanol.

      It's starting to smell like snake oil :-)

      Seriously, though, I'm not sure how that applies.... A gun is a device designed to kill things by making puncture wounds. It is safe within those parameters. Of course, those parameters are incompatable with a ride on an airplane. A battery is a device designed to store electricity. If it is safe within those parameters, it is a perfect thing to have on an airplane.

    You're both right. There are natural gas deposits in many areas that don't have any oil. However, there is also quite a bit of methane as a "byproduct" of oil production. Have you ever seen those flames shooting off of the offshore oil rigs? They're not burning oil, that's methane.

    When drilling for oil, methane tends to collect in the same areas as the oil. Usually there is a "space" at the top of the oil resevoir, especially after you start drilling, that is filled with the stuff. They don't have the capability to capture & store the stuff because there's just too much of it. But it's also dangerous to just let it leak out around everything. The solution, controlled burn!

    I've often thought it would be nice to capture all of that wasted energy. Not necessarily in the form of natural gas, but perhaps as electricity. I wonder if we could just place some gas turbines on the rigs & then run some wires to the shore (depending on where they are obviously). You've gotta think this is a more cost effective solution for the oil company than just burning the stuff off & losing that possible revenue.

    Or perhaps producing Hydrogen.....
