Fujitsu fuels the hard cell

Portable devices from notebooks to mobile phones are set to get tipsy on methanol fuel cell technology if Fujitsu has its way.

Fujitsu Laboratories has announced the development of a new fuel cell material technology that uses highly concentrated methanol as a fuel source, as well as a prototype power unit that incorporates the technology. This technology enables much higher power capacities for passive micro fuel cells and means that mobile devices such as notebook PCs, PDAs and mobile phones should be able to run longer. As notebook PCs, PDAs and mobile phones deliver higher performance, they place greater strain on electrical power. Lithium-ion (Li-ion) batteries commonly used today are approaching the limits of their capacity. Micro fuel cells use alcohol solutions as fuel. In terms of energy density, these fuel cells offer up to 5-10 times the power per unit weight of a Li-ion battery. Fuel cell technology still has to overcome some design issues before it will become a reality however.
