NTT DoCoMo today announced a revolutionary new fuel cell charger for its FOMA series of 3G phones. It’s still in the testing phase, but is expected to greatly increase the possible usage time of FOMA mobile phones.

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.

Two photos of the fuel cell are available after the jump.
