NEC Corporation has announced the development of a fuel cell with 20% greater power generating efficiency than the PC built-in fuel cell demonstrated earlier this year at Nano Tech 2003.
A prototype notebook PC incorporating this compact fuel cell has also been produced. NEC will demonstrate this prototype notebook PC with a built-in fuel cell at WPC EXPO 2003, an international PC exhibition to be held from September 17 to 20 at Makuhari Messe in Chiba Prefecture, Japan.
The newly developed 900g fuel cell is said to boast the world’s highest output density of 50mW/cm2. The fuel cell can also operate for approximately 5 hours using 300cc of methanol fuel with a concentration of approximately 10%.
NEC plans to market a notebook PC (weighing in at 2kg) with a built-in fuel cell by the end of 2004. It also intends to make a notebook PC equipped with an internal fuel cell that offers 40 hours of continuous operation available by the end of 2005.
