Fuels cells could power cell phones by 2007

Direct Methanol Fuel Cells (DMFC) that mix methanol, air and water to produce power may be used in cell phone as early as 2007.
A fuel cell technology that will offer a quick fix for dead or dying mobile phone batteries could be available in Japan by 2007, Japan's two biggest mobile communications carriers said today at the Wireless Japan 2005 Expo.
Direct Methanol Fuel Cells (DMFC), which typically work by mixing methanol with air and water to produce electrical power, have for years been promoted as an alternative to lithium ion batteries used in notebook PCs and other portable electronics gear.
A number of Japan's biggest consumer electronics companies have been developing DMFCs, but the prototypes so far have been too big and bulky or incapable of producing enough power to be commercialized.
Japan's mobile phone vendors spent years trying to get the battery life of third-generation (3G) mobile phones to match that of the country's 2G digital phones.
The device is close to making the cut for those of the carrier's nearly 50 million subscribers who are looking for a quick power fix, said Kazuhiko Takeno, a manager in the company's technical support group.
The recharger, which is a cradle design, is expected to be commercially available sometime in mid-2007, Takeno said, noting that the version on display at the Expo is a big improvement on an earlier model shown in September.
While it's about the same size as the older model, the new prototype has enough power to recharge a mobile phone battery three times, he said.
The prior model could recharge a battery only once.
Fuel-cell technology is also looking viable for KDDI's customers, according to Youichi Iriuchijima, an assistant manager at the company's IT development division.
At October's Ceatec Japan 2004 exhibition, Iriuchijima showed prototype rechargers from Hitachi Ltd. and Toshiba Corp., promising that improved versions would be available in 2006.
