Toshiba is working on portable fuel cells for mobile phones and PDA's. The approach isn't to jam a fuel cell into a mobile, but to make a device that can recharge the phone (a portable power plant if you will). So far they have made a 4.6oz fuel cell that can run for 20 hours, which is about 6 charges for a typical phone according to the company.
