Bacterial fuel cells may power cell phones, laptops

Scientists at the John Innes Centre claim to have developed a bacterial enzyme that works like a miniature hydrogen fuel cell. Conventional fuel cells use platinum catalysts to release electrons; the bacteria do the same thing using an iron-sulphur reaction. The bacterial batteries will reach the market sometime in 2006.
If you are fed up with carrying a bulky mobile charger everyday in your wallet, then this one is for you.
A new technology will enable mobile users to get connected to the world with the help of bacteria.
According to the report published in the journal Nature, Prof Chris Pickett and his colleagues at the John Innes Centre claim that they have built the active part of a bacterial enzyme that works like a miniature hydrogen fuel cell.
The world's first efficient bacterial battery, as they say, will recharge your cell phone or any other portable electronic device within no time.
The research could help scientists to replace the expensive platinum catalysts in fuel cells that break up molecules of hydrogen gas, releasing electrons that generate an electrical current.
"In nature iron-sulphur enzymes catalyse a range of important chemical reactions that industry can only do by using precious metal catalysts and/or high temperatures and pressures," the Telegraph quoted Prof Pickett as saying.
The bacterial battery will hit the market in mid 2006 and could be used in environments where it is difficult or costly to charge the batteries.
