KDDI shows improved fuel cell mobile phones

By Liam McNulty

Back in July of 2004, Toshiba and
Hitachi and
began working on getting fuel cells in mobile phones. It looks like things are coming along nicely, as KDDI
has announced prototypes of the fuel cell versions of the "A5509T" and "W32H" handsets. It's also nice to see that the companies took two different approaches: Toshiba went for lifetime through a hybrid system, bringing the A5509T's talk time to nearly 8 hours or idle time to, oh, only 28 freaking days. Hitachi, on the other hand, merely matched the W32H's size and battery life with a fuel cell.
