Toshiba Corporation has announced the prototype [image] of a highly compact direct methanol fuel cell (DMFC) that can be integrated into devices as small as digital audio players and wireless headsets for mobile phones. The new cell measures in at a compact 22 x 56 x 4.5mm (maximum of 9.1mm, for the fuel tank), and and weighs only 8.5g. It can power small hand held devices for up to 20 hours on a single 2cc charge of highly concentrated methanol.
