Toshiba Corp. (Japan) reported that Guinness World Records has authenticated its direct-methanol fuel cell (DMFC) as the world's smallest DMFC. The thumb-size fuel cell is 22 mm wide, 56 mm long and 4.5 mm high.

The fuel cell outputs 100 mW of power and can power a small music player for as long as 20 hours on a single 2 cm³ charge of concentrated methanol. Toshiba plans to introduce commercial samples of its DMFC for small hand-held electronic devices in 2005.
