30th September 2004 - NTT DoCoMo, Inc. announced
today the joint development of a prototype micro
fuel cell for 3G FOMA handsets. The prototype,
manufactured by Fujitsu Laboratories Ltd., is
expected to greatly extend FOMA handset usage
time once it goes into commercial production.
The micro fuel cell is aimed at meeting user
demands for more convenient handsets with greater
power capacity, as well as reduced environmental
impact.

30th September 2004 - NTT DoCoMo, Inc. announced today
the joint development of a prototype micro fuel cell
for 3G FOMA handsets. The prototype, manufactured by
Fujitsu Laboratories Ltd., is expected to greatly extend
FOMA handset usage time once it goes into commercial
production.
The micro fuel cell is aimed at meeting user demands
for more convenient handsets with greater power capacity,
as well as reduced environmental impact.
Power consumption demands are rising as FOMA users
take advantage of new services and handset features,
including flat-rate monthly billing for data services,
such as i-motion™ and i-appli™, and videophone.
DoCoMo is addressing this issue in part by increasing
the capacity of its lithium-ion batteries, the most
commonly used battery in handsets today.
The micro fuel cell is a standalone device shaped like
a cradle for recharging handsets. It generates electric
power by combining hydrogen and cheap, environmentally
harmless methanol to produce a chemical reaction. Hydrogen
ions are extracted from the air via a layer sandwiched
between positive and negative electrodes.
The prototype has the same basic specifications of
other FOMA handset rechargers and will be compatible
with all FOMA handsets. Further development of the prototype
is expected to be completed by the end of fiscal 2005.
