Sony’s Micro Hybrid Fuel Cell System
Sony’s new fuel-cell system is direct methanol type and uses methanol as fuel. Also, it is an active fuel-cell system, which controls fuel supply with a pump. The system is hybrid type with the output supplemented by a Li-polymer secondary battery. And it can deal with steeply rising peak powers of mobile devices.
Though Sony did not reveal the output density of the system, its instantaneous output can be as high as 3W, the company said.
“We have been aiming to mount (a fuel-cell system) in mobile devices and finally reached a level of commercial design, 3W is pretty enough for peak powers of mobile devices,” an engineer for Sony Material Laboratory said.
Also, its use efficiency of energy is high enough that 14 hours of 1seg movie can be continuously played by general mobile phones with 10mL of methanol.
