Recent technology in the development of fuel cells promises to eventually replace or at least supplement today's laptop batteries.
Fuel cells, instead of storing power, generate electricity by breaking down methanol via an electrochemical process. The cells can be recharged by topping them up with methanol from a cartridge.
Recently, Toshiba, Hitachi, Fujitsu, Samsung and Sanyo, among others, have shown prototypes that suggest that the technology is just around the corner.
Toshiba began fuel cell development about four years ago. Three key areas that need work are size, noise and weight, prior to commercialisation. However the company aims to have a commercial version out in 2007, according to Tomoaki Arimura of Toshiba′s Methanol Fuel Cell Group.
