Samsung Developing Water-Powered Cell Phone Battery

Samsung Electro-Mechanics has developed a micro-fuel cell and hydrogen generator that runs on water. When the handset is turned on, metal and water in the phone react to produce hydrogen gas. The gas is then supplied to the fuel cell where it reacts with oxygen in the air to generate power. Other fuel cells need methanol to produce hydrogen, while Samsung's needs only water.
Since micro-fuel cells can generate up to three watts of electricity, they could be used in mobile devices. The new fuel cell could power a handset for ten hours, twice as long as rechargeable batteries.
