Mini fuel cells are a hot topic in the electronics industry as a whole, and companies such as Hitachi, Panasonic and Toshiba showed a number of promising products that are soon to be commercialized. Now Sony follows with a (hybrid) fuel cell system that is sized at just 50x30mm.

The system consists of a fuel cell, which uses methanol as fuel, and a Li-polymer secondary battery. Users can view 14 hours of digital TV on a cell phone with just 10ml of methanol.

Sony claims the prototype features a maximum output of 3W and says it will be mass-produced for use in mobile devices in the future.
