(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.

(InfoWorld) - Telefonaktiebolaget LM Ericsson believes companies will be able to make 3G (third generation) mobile phones for as little as $70 next year as component makers step up their efforts to simplify the handsets, an executive said. The low-cost 3G handset would likely allow users to browse the Internet, and use messaging and voice services, according to Sean Gowran, president of Ericsson Taiwan. Low-cost handsets have been aÂ buzzword in the industryÂ for the past few years as a way to tune more people into the existing global GSM (Global System for Mobile Communications) wireless network. The GSM Association (GSMA) has evenÂ launched a contestÂ to inspire mobile phone makers to create a low-cost 3G handset, an idea similar to their contest a year ago aimed at producing a GSM handset for under $30.Â Motorola won that contest. Demand for the low cost GSM phonesÂ has been brisk in emerging markets such as China and India this year, where mobile phone use is growing at frantic pace. India recently announced its strongest month ever for wireless subscriber growth, at 6.71 million people in October. The figure brings its total to 136.22 million subscribers, up from 75.9 million at the end of last year, according to the Telecom Regulatory Authority of India. By 2010, there will be 405 million mobile phone subscribers in India, according to market researcher iSuppli, thanks to ultra-low-cost handsets. In China, theÂ number of wireless handset usersÂ climbed to 449.02 million at the end of October, up from 393 million at the end of last year, according to the Ministry of Information Industry, that country's telecom industry regulator. Ericsson believes that efforts to reduce costs have had a big impact on the mobile phone industry. Cheaper components, and fewer components will be vital to efforts to develop a $70 3G handset. "The number of components is dropping dramatically," said Gowran. Fewer components reduces manufacturing complexity and can allow handset makers to reduce materials costs. The difference between a low-cost 3G handset and a high-end one will be huge, he said. An advanced handset with all the latest features, smart phone computing capabilities, the latest digital camera functions, multimedia applications with plenty of memory and the ability to use push mail and mobile TV will still be more expensive at around $500. Gowran also clarified that the $70 target is not an end-user price, but a cost-to-make price, and that Ericsson would not be producing such phones since it does not build mobile handsets anymore. The Sony Ericsson Mobile CommunicationsÂ joint venture with Sony took over all Ericsson handset production, and Gowran said he could not speak on behalf of the company. The original talk regarding low-cost 3G handsets was given by Robert Puskaric, the head of the mobile platforms division at Ericsson, at the International Telecommunication Union (ITU) Telecom World 2006 conference in Hong Kong. The exhibition runs through Friday.
