A direct methanol fuel cell created by Toshiba has been certified in the 2006 edition of Guinness World Records as the world's smallest DMFC. The device, which outputs 100 milliwatts of power and can power a small music player for as long as 20 hours on a single 2 cubic centimetre charge of highly concentrated methanol, is only 22 millimetres wide, 56 mm long and 4.5 mm high, making it the smallest fuel cell in the world. Toshiba plans to introduce commercial samples of the DMFC for small handheld electronic devices in 2005.
