Toshiba and Hitachi to Make Micro Fuel Cells for Mobile Devices

Keywords: Environmental Technology Manufacturing industry Renewable Energy 

In Japan, Toshiba and Hitachi have both started development of micro fuel cells for notebook computers and other portable devices. They are targeting to launch micro fuel cells as early as 2003.

The micro fuel cells enable the use of electronic devices for a much longer period of time without recharging than rechargeable batteries and are suitable for advanced information appliances that require a lot of power, for instance to transmit moving images. Companies in the United States are also trying to fabricate a prototype micro fuel cell. Competition for development around the world is going to be fierce.

Toshiba and Hitachi's micro fuel cells generate electricity by directly supplying methanol to a special membrane. The fuel for the fuel cells will be sold in cartridges at convenience stores. The price is expected to be at the same as that of rechargeable batteries currently on the market.
