Notebook fuel cell Hannover, Germany March 10, 2005 Tell us your opinionCeBIT: Another fuel cell prototype has been launched but this time it comes with a firm commitment to launching a finished product this year Taiwanese company Antig Technology(勝光科技) has developed a compact prototype fuel cell integrated into a notebook PC. The prototype, which is the size of a CD-ROM disk and is pictured below, was demonstrated at CeBIT trade show in Hannover, Germany, on Thursday. The company also showed off a prototype 12W fuel cell for notebook PCs and a prototype fuel cell charger for mobile phones. Commercial versions of the prototypes for notebooks and mobile handheld devices are expected to be available by late 2005.
