The Toshiba fuel cell phone is based on the A5590T handset. The device is powered by a compact fuel cell (methanol) and fuel tank on the back, in addition to an internal lithium ion battery. Apparently the phone’s battery life is 2.5 as long as your conventional lithium battery cell phone.
The Hitachi fuel cell phone is based on the W32H (pictured) and uses a comparable system to that of the Toshiba. Even though an additional fuel source has been added, the Hitachi supposedly phone maintains ‘a close’ to original size.
It seems as though not all of the details have surfaced, but we’ll keep you posted as they become available.
