French researchers have invented a hydrogen fuel cell that can be used in mobile phones as a back-up power supply.
The fuel cell is miniature in size and is designed to be carried in a belt pouch or pocket. The gadget has been in the works since 2005 with a semi-conductor group called STMicroelectronics.
The cartridges are being developed by Bic – the same company who makes also those ubiquitous razors, lighters and pens.
Designed to work as a hybrid system, the phone draws on the ordinary battery first and uses the fuel cell once it runs dry.
The greatest benefit of the cartridge is that despite its small size, it will supply power equivalent to three to five recharges, getting you through weeks without a charger or perhaps even weeks away from an electricity supply.
The fuel cell is not due to hit the market until early 2010 and the price has not yet been disclosed.
