Japan via Fujitsu has been able to do wonders with fuel cell technology. What makes these fuel cells so awesome is that they are not only non-threating to the environment, they also happen to be rechargeable as well.

The prospect of fuel cell technology for powering small devices has come one step closer. Japanese electronics giant Fujitsu says it has tripled the charging capacity of fuel cells for mobiles and has now developed a commercial prototype with the Japanese telco DoCoMo.

Fuel cells are not only rechargeable but also environmentally friendly. Unlike traditional devices that are based on lithium and have to be thrown away when exhausted, fuel cells run on methanol that produces only water as a waste product and can be refilled. However, R&D departments have tried for many years to get sufficient power from a fuel cell device to make it marketable. [Read the rest]
