If small, low-output fuel cells can power media players, then why not cell phones?
Engineers at Angstrom Power and Motorola decided it was time to include these long-neglected devices in the hydrogen economy. With that in mind, the two companies joined forces to create a prototype of a mobile phone powered by hydrogen.
Unlike the methanol-based Toshiba fuel cell media player, the Motorola-Angstrom device uses water to make hydrogen. According to CNET, here hydrogen is made "with a desktop fueling station and then inserted into a metal hydride storage container on the phone." The molecules then pass through a fuel cell, giving off their electrons to power the phone.
The report also points out that solar panels can also be used for water-to-hydrogen energy production, making the phone as green as can be.
