(InfoWorld) - NTT DoCoMo is showing at this week's Ceatec show in Japan a prototype fuel cell that it's developing with a Japanese startup for use as a cell-phone recharger. The polymer electrolyte fuel cell (PEFC) uses hydrogen gas as a fuel to produce electricity and is a compact 24 millimeters square, 70mm long and weighs 45 grams. The fuel cell isÂ under development by Aquafairy, a startup spun out of Nitto Denko to work on the technology. NTT DoCoMo recentlyÂ acquired a 36.5 percent stakeÂ in the company for an undisclosed sum. It can deliver enough power to recharge a cell phone three times before requiring a hydrogen refill. While it's still some way from being a commercial product, the fuel cell is completely different to what NTT DoCoMo had on show at Ceatec 2005. A year ago the company wasÂ displaying a direct methanol fuel cellÂ (DMFC) that was developed by Fujitsu Laboratories andÂ built into a cradleÂ into which a cell phone could be placed for recharging. DMFCs are based on a different chemistry from the PEFC on show this year. They typically work by mixing methanol with air and water to produce electrical power. For companies like NTT DoCoMo a future goal remains a fuel cell small enough and safe enough to be built directly into a cell phone. But the technology isn't at that stage yet so the first commercial fuel cell devices will likely be recharges that replenish the Lithium Ion battery inside of the phone but offer the advantage of being able to do so anywhere -- not just within a couple of meters of a wall socket.ADVERTISEMENTMAKE SOA REAL WITH IBM WEBSPHERE PODCASTStreamline processes and maximize efficiency within a proven service oriented architecture.
