Micro fuel cells have the potential to provide much longer run-times for portable consumer electronics, and can be 'recharged' by replacing the fuel cartridge, unlike a battery-powered device which requires both time and an electrical outlet. A promising fuel offering these advantages is methanol or a methanol/water solution. Other fuels are under investigation.

• Methanol Fuel Cells (MFCs) will be used to replace or charge rechargeable batteries in the near future as electrical power sources for portable consumer electronics like laptop computers, mobile phones, pda's, etc.
• MFCs will provide significant longer run-times for portable consumer electronics currently powered by batteries.
• MFCs can be instantly 'recharged' by simply replacing the methanol cartridge, unlike a battery powered device which needs time and an AC power outlet. This eliminates the need for consumers to carry electrical cords or adapters.
• Fuel cartridges will have smaller volumes and lower weights than spare batteries. They will also not loose energy during storage.
