TOKYO-Fujitsu Laboratories Ltd. and NTT DoCoMo Inc. said they have developed a prototype of a high-capacity micro fuel cell and an external recharger for FOMA handsets.
The company said the concentration of methanol fuel used for the prototype design was raised from 30 percent in previous fuel cells to a concentration of more than 99 percent. This allows the prototype to charge up to three lithium-ion FOMA handset batteries with 18 cc of methanol, said the company.
