I was researching about this phone too, it sounds really interesting! Here's some info that I want to share with you.
Fuel cell maker Angstrom Power and mobile phone maker Motorola have teamed up to create a prototype mobile phone that runs on a hydrogen fuel cell.
Hydrogen is produced by cracking water molecules with a desktop fueling station and then inserted into a metal hydride storage container on the phone and when the hydrogen molecules pass through a membrane in the fuel cell, electrons are stripped away and get diverted to run the phone.
With a hydrogen fuel cell, you never have to go to the store to get fuel feedstock. You get it out of the faucet. Basically, you can think of it as a water-powered phone.
Here is the Moto's prototype hydrogen-powered phone
