KDDI, Toshiba Corp. and Hitachi Ltd have co-developed prototype mobile phones powered by next-generation fuel cells.

Developed by KDDI and Toshiba, the prototype mobile phone based on the au handset A5509T uses a hybrid type system with power supplied by a compact fuel cell and fuel tank at the back of the phone unit, and an internal lithium battery. The system uses high-concentration methanol to achieve a battery capacity of 2.5 times the conventional value with a single refill.

The fuel-cell mobile phone developed by KDDI and Hitachi is based on the au handset W32H. It uses a hybrid type system with power supplied by a compact fuel cell on the side with the LCD display, and an internal lithium ion battery, according to the press release. The concept is a "fuel-cell handset of the near future" that features a fuel cell that can be refilled from a compact cartridge.

The three companies hope to release practical fuel cells for mobile devices by the end of this fiscal year.

KDDI, along with it's partners, is set to exhibit the prototype mobile phones at CEATEC JAPAN starting October 4.
