NEC's experimental direct methanol micro fuel cell for portables that uses nanocarbon material for its electrodes.
TOKYO - Japanese computer giant NEC Corp. Monday revealed a prototype of a laptop computer that runs on a methanol fuel cell instead of a rechargeable battery, and said it will start selling it next year.
A number of other companies are developing similar fuel cells, which promise to power electronics ten times longer than the lithium-ion batteries currently in use.
