During the second quarter of 2008, Sony introduced its hybrid fuel cell prototype that's so small it can fit in the middle of your palm. It was, of course, the mere core material of various devices Sony developed since then. At the FC EXPO 2009 event to be held at Tokyo Big Sight this end of February, Sony will be showing off what became of its fuel cell as well as its intriguing sugar-powered battery presented around October of 2008.
Sony's fuel cell, as was mentioned before, uses methanol as the main source of energy, supplemented by an auxiliary lithium-ion battery. Two fuel cell models exist - a portable external version, complete with a leather lanyard and a USB connection to charge gadgets and an internal model to be used like a conventional battery. Both iterations of the fuel cell can provide a cell phone up to a month's worth of charge. Meanwhile, Sony's updated sugar-powered battery exhibits an increase in output compared to the original version, but retains the same capacity to power devices with glucose-rich materials such as soda.
