What if you could power your mobile phone with nothing more than good old H2O? That would really be something!
Angstrom Power and teammate Motorola seem to have developed a way to power cellphones with a hydrogen fuel cell. Of course, it's still in the testing phase, with a prototype, but the concept is certainly interesting. Imagine, all you’ll need to do is fill up your cellphone with water – and voila, it’ll start working again.
Angstrom has already developed an LED flashlight that runs on a similar concept of a hydrogen fuel cell. The good thing is perhaps we can look forward to a cleaner planet in the not-so-distant future.

More details about how the fuel cell works and how hydrogen is refilled, the power output etc should have been explained..
