Platinum 'nano-raspberries' may hold the key to methanol fuel cells
Could our future cars be powered by methanol fuel cells, rather than gasoline engines or electric batteries? Perhaps. The National Institute of Science and Technology (NIST) is making the oil alternative more viable by developing a fast, simple way of producing platinum "nano-raspberries," which contain tiny clusters of nanoparticles. Each tiny piece of matter, measuring between 1 and 100 nanometers, acts as a catalyst inside fuel cells to help convert liquid methanol into electricity. The clusters are called nano-raspberries because of their fruit-like shape, and they're particularly effective due to their high surface area.
Brookstone fuel cell USB charger to keep phones powered for two weeks, Engadget editors happy
If there's a pain that Engadget writers know all too well, it's running out of battery life for a smartphone when we need it most. Say, at a major trade show. That's why we're enthused to hear of an upcoming fuel cell USB charger that Lilliputian Systems is developing for Brookstone. The lighter fluid-filled tank should provide up to 14 full charges for your phone before you need to spend a few dollars to top up, or two weeks if you power up daily -- we'd call that about two CES' worth in our lingo. Better still, using a solid oxide membrane on silicon not only makes a long fuel cell runtime possible, longer than we've seen for methanol, but makes the phone-sized pack safe to carry on the airliners we ride entirely too often. Pricing has yet to be sorted out, but with Brookstone stores likely to start carrying the fuel cell before the end of the year, it should be ready just in time for our next big trip to Las Vegas.
Toshiba misses another consumer fuel-cell launch date as expected
It's the end of March and you know what that means? No Toshiba fuel cell battery charger for you, that's what. Toshiba's launch of the first direct methanol fuel cell-based (DMFC) charger for your miscellaneous gadgets has been delayed "a few months" due to problems in acquiring unspecified components. Why do we care? Easy, DMFCs produce electricity via chemical reaction between methanol, water, and air. When the power runs out you just top-off the methanol or drop in a new cartridge and you're good to go. Also, this DMFC charger is just the first step towards DMFC batteries for cellphones and laptops that Toshiba says are still on track to launch before the end of March 2010. Not that we'd be surprised by further delay -- we've been hanging on to the promise of fuel-cell battery launches for years now... what's another slip.
Sony shows off its latest fuel cells and cola-powered batteries
In two days the world's largest fuel cell exhibition, FC EXPO 2009, kicks off in Tokyo, and Sony will be there showing off the latest revision of its hybrid fuel cell technology. The system contains both a methanol fuel cell and a Li-on battery, enabling it to intelligently switch between power from the battery, fuel, or even both under high-draw circumstances. Sony will have two sizes on display: a portable model (above, with real leatherette lanyard) that could keep you talking on your celly for a week, and a heftier "interior" model that could do the same for a month. The company's even attached a bottle of methanol to a wireless speaker, resulting in infinite placement possibilities and a groovy light show to boot. If that weren't enough, the company will be demonstrating an updated, more efficient version of its sugar battery, which can be powered by plain 'ol Coca-Cola -- and you thought that stuff was only good for making your nephews run.
Toshiba powers cell phone with methanol fuel cell -- no, you can't have one
Toshiba continues to tease us with its prototype liquid fuel cell-powered gadgets: last year it was a Gigabeat media player, and at this year's CEATEC you can check out a direct methanol fuel cell (DMFC) that's been crammed inside a cell phone, lending it a robust six hours of talk time (compared to the paltry three or four hours of a traditional battery). Toshiba won't reveal the capacity of the DMFC, but they have said that a 50ml cartridge is good for about 15 refills. No release date yet, but the phone "might" be available "as early as next year." In the meantime, enjoy this picture of a woman holding a flip phone with "DMFC" clearly visible on the display.
Sharp reveals world's most densely powerful methanol fuel cell -- still can't buy it
We've been huffing the vaporous promise of methanol fuel cells for so long now that we sold all our furniture and live in a cardboard box. Nevertheless, Sharp's in a tizzy over its direct methanol fuel cell (DMFC) prototype. Sharp's cell is able to provide 0.3 Watts of power per cubic centimeter making it the world's most powerful DMFC cell for its size. Availability? Sharp has no idea but "it won't be commercialized soon," according to a spokesperson. Kudos for honesty, but that gnawing angst for a refillable battery replacement for traditional lithium-ion batteries continues to taunt us.P.S. Sharp didn't offer any photos with the press release so we tossed in an old Toshiba concept just to annoy them.[Via PCWorld]
Sony creates micro-sized fuel cell system
Finally we can all sleep at night, safe in the knowledge that Sony has created a prototype fuel cell system that fits in the palm of your hand. The combination lithium-polymer battery, backup battery, and control circuit are destined for future mobile devices. According to a company engineer, "We have been aiming to mount (a fuel-cell system) in mobile devices and finally reached a level of commercial design." The tiny power-pack uses methanol as a fuel and controls supply with a hybrid pump, which allows it to regulate the amount of power used based on a system's needs. The company claims that just 10ml of methanol can power a mobile device through 14 hours of 1seg movie watching. Sure, it sounds good on paper, but does this mean soon we'll have to visit tiny, methanol refilling stations manned by a team of mice in jumpsuits? Probably not.
Researcher touts "practical fuel cells" for portable electronics
There's certainly no shortage or researchers and companies promising to bring fuel cells into everyday gadgets, but Ronald Besser of the Stevens Institute of Technology seems to think he has a system that can stand out from that pack. According to MIT's Technology Review, Besser's proposed system consists of a cylindrical design with "combustor" at the center that facilitates all the necessary reactions to convert methanol into hydrogen. Apparently, that design not only allows for the fuel cells to be made smaller, but more efficient as well. While it seems to still just be on the drawing board, Besser says the system could eventually allow for laptops to run for upwards of 50 hours, and could be made small enough to power other portable electronics as well. In the meantime, however, you may want to keep an eye on some of the systems a littler closer to reality.
Samsung's one-month Fuel Cell piggy given a real purty mouth
No word on a production run, but we thought you'd like to peep the latest iteration of DMFC (direct-methanol fuel cell) technology coming out of Samsung. If nothing else, they've at least cleaned up the design of that dock we last peeped back in December. A good sign that they're still intent on releasing this one-month, refillable battery by the end of 2007.
Powerless filtration system increases fuel cell efficiency
While we've been seeing methanol fuel cells pop up in all kinds of concept devices for a while now, there have been precious few actual shipping products that get their juice on with a fuel cell. That might be slowly changing, as a research team at the National Tsing Hua University in Taiwan has come up with a novel filtration system that increases the efficiency of methanol cells to potentially usable levels. The system, which is 10 times more efficient than conventional waste pumps, features a series of 100 50-micron holes that allow waste CO2 to escape out of the cell, while excess water is pulled off by a hydrophobic Teflon ramp (boy do we love those hydrophobic Teflon ramps!) that drives H20 molecules away from the methanol and into a collector. Since this method doesn't require any power to work, it's well-suited to cell phones and laptops, as the cells can be made smaller and quieter. While this doesn't mean we'll be seeing fuel cell Zunes anytime soon, you can bet those guys in Texas with the booze-powered robots just crossed a big X off their dev charts.(Photo is of an unrelated Toshiba fuel cell concept.)[Via DailyTech]
Casio develops methanol-based micro liquid fuel cell
Speaking of liquid fuel, we've just caught wind of another liquid fuel cell that may be available a little sooner than LG's ebook concept laptop. Casio has apparently developed a new prototype fuel cell that could make our long-standing desire to live a totally wireless life possible. According to DigitalCameraInfo, Casio's new technology draws in methanol "to produce an electrolyzed liquid that is emitted as hydrogen gas." Then, apparently after some chemical hocus-pocus, the power source can remain autonomous and continuous. The Cas says that it's made this system work in a digital camera and also said that it will be shipping the micro fuel cell technology beginning next year, which we assume means they've worked out the volatility issues we mentioned before. Assuming all goes as planned, our next question is: where's our nearest supplier of methanol?[Via DigitalCameraInfo.com]
Suzuki Motors unveils MIO: the fuel cell-powered wheelchair
If you're trying to get away from that gas guzzling wheelchair, but feel a bit awkward rolling in the less-than-glamorous solar-powered edition, Suzuki Motors has got your back. Taking a leap forward from its previous lead-acid battery-powered electric wheelchair, the MIO is a motor-driven cart that gets its juice from an ultra-green fuel cell. The cell works in conjunction with a "large capacity Li-ion secondary battery," and while we aren't certain of how quickly this bad boy can streak down the quarter mile, it can supposedly cruise for 25 miles on a single fill up (four liters) of methanol solution. Aside from the power source, the MIO sports armrests that serve double duty as safety barriers, ergonomic handlebars, a comfortable mesh seating surface, and even an LCD panel that shows such useful data as fuel level and power status. While Suzuki insists the unit is simply a prototype, and refuses to hand out pricing details while it "judges consumer interest," the MIO should still be a bit easier to acquire than the sold out Tesla should it ever hit stores.[Via Far East Gizmos]
