NTT DoCoMo Develops Fuel Cell for 3G Handsets

NTT DoCoMo announced a partnership with Aquafairy Co. to develop a micro fuel cell for its 3G "FOMA" handsets. The companies have succesffully demonstrated a prototype recharget based on a polymer electrolyte fuel cell (PEFC).



NTT DoCoMo described the fuel cell as the smallest in the world with power output of 2 watts. The recharger combines DoCoMo's recharger technology with Aquafairy's thin film power unit technology and catalyst for producing hydrogen from water. The simple hydrogen-producing mechanism and power units make the recharger less than one-fourth the size and more than twice as powerful as the methanol fuel cell prototype that DoCoMo unveiled on July 6, 2005. The easily portable recharger can charge a handset several times, and the recharging time is approximately the same as an AC adapter.
