Fuel cells, which operate on the reverse principle of the electrolysis of water, are considered as one of the promising electricity generating technologies that are clean and sustainable.*1 Hitachi, Ltd. is working to develop a portable fuel cell that generates electricity by supplying a methanol solution and air to electrodes. One of the obstacles was improving the energy output capacity; however cumulative improvements in nanotechnologies made it possible to create a trial concept model that uses a cartridge as a supply system of fuel.*2 Still, a constant challenge is ongoing to apply the technology in practical uses as early as possible, so that it can be a power generation system that will work &quat;anytime, anywhere,&quat; for the whole range of portable devices such as mobile computers. (First sales are expected in 2006.)
*1 :
A reaction of methanol (methyl alcohol) and air emits only water and carbon dioxide.
*2 :
The cartridge technology is being developed in cooperation with Tokai Corporation.
