TOKYO-Guinness World Records officially certified Toshiba Corp.’s direct methanol fuel cell (DMFC) as the world’s smallest DMFC.
The fuel cell is designed for integration into devices as small as digital music players. The cell is about as long and wide as a thumb, measuring 22 by 56 by 4.5 millimeters. The prototype is efficient enough to power an MP3 music player for as long as 20 hours on a single 2cc charge of highly concentrated methanol.
“We are really honored and delighted that an organization as respected as Guinness World Records has certified our fuel cell as the world’s smallest DMFC,” said Kazunori Fukuma, managing director of display devices and components control center for Toshiba. “This is welcome recognition of our efforts to stay a step ahead of our competitors in fuel-cell miniaturization and operating efficiency. We will continue to develop even more compact, more efficient DMFC that can power the smallest portable devices on the market.”
Miniature fuel cells have gained a notable amount of interest in the wireless industry as a replacement for standard batteries.
