KDDI used the CEATEC conference in Tokyo as a platform to show off its updated prototype methanol fuel cell-powered mobile phone. In addition to the methanol, the fuel cell includes a lithium ion battery to help the unit deal with surges in energy use.

The battery is optimized to offer users 320 hours of power, a significant increase over current standard battery capacities. Of course the main benefit of such a power source is that the methanol can instantly be refilled (as shown in the photo above) rather than waiting for a power outlet to gradually recharge your mobile phone. KDDI hopes to have a sellable version of this technology on the market within the next few years.
