Everybody knows that fuel cells will change the face of the electronics industry once they finally start making their way into electronic devices. Recently, Sony has unveiled its own ultra-small hybrid fuel cell system which seems to be small enough to fit in one hand.

It measures 50mm x 30mm and combines a fuel cell, Li-polymer secondary battery and a control circuit. It looks like this is the first time Sony showed a complete fuel cell system that has a control circuit and secondary battery. The company expects to commercialize it and a Sony’s engineer said : ?We have been aiming to mount (a fuel-cell system) in mobile devices and finally reached a level of commercial design.? The fuel cell runs on methanol.
