Toshiba Corporation has developed two prototype direct methanol fuel cell (DMFC) units and begun tests to validate their operation with mobile audio players. Each unit integrates the DMFC that Toshiba announced in June 2004 as the smallest ones available.
The new fuel cell units have an output power of 100mW and 300mW and have been applied to a flash-memory-based digital audio player and an HDD-based digital audio player, respectively
The 100mW unit, similar in shape and size to a pack of gum (23mm x 75mm x 10mm), can power the flash-based player for approximately 35 hours on a single 3.5ml charge of highly concentrated methanol, the fuel that drives the electricity producing chemical reaction in the fuel cell. The 300mW unit is 60mm x 75mm x 10mm and delivers enough power to keep an HDD-based audio player running for approximately 60 hours on a single 10ml charge.
We won’t see these till at least 2007 according to the article but wow!
Two and a half days of power for a Hard Drive based audio player on a 10ml fuel cell!
Bring it on!
