IBM and Sanyo Electric unveiled initial plans for a prototype micro direct methanol fuel cell system for IBM ThinkPad notebooks.
Leveraging Sanyo's latest advancements in fuel cells that increase the longevity of notebook batteries, IBM and Sanyo jointly developed
a basic design of a fuel cell power source.
Based on the design, the companies developed a prototype fuel cell system that could supply up to 8 hours of power per cartridge on
current and future ThinkPad models.
SANYO's system was designed to be compatible with most current ThinkPad models without the need to alter the notebook design.
The fuel cell system also includes an auxiliary bay IBM's Ultrabay Slim Battery to supplement peak power consumption for business
applications. In addition, the auxiliary bay could be used to make the power supply even more versatile by charging an UltraBay Slim
The fuel cell system could enable ThinkPad notebooks to run without draining PC battery power.
"There are a number of vendors developing fuel cell battery prototypes for PCs and mobile devices, but the combination of IBM's
first-class ThinkPad notebooks and Sanyo's leadership position in the technology will accelerate research and development in the
field," said Peter Hortensius, vice president, IBM Personal Computing Division. "We do not focus simply on the 'wow factor' of fuel cells
-- we see it as a powerful enabler that could support a wide variety of business applications. These companies are collaborating to help
carry ThinkPad notebooks to the next generation of power supplies, while supporting the highest levels of business productivity."
The IBM PC Division's ThinkPad development team has focused on new behavioral usage models for fuel cells in mobile computing,
such as docking stations used for office 'hoteling' concepts and the deployment of notebook computers in locations remote from
traditional power sources.
"SANYO as the world technology leader in rechargeable batteries, has been conducting research and development of fuel cells. I am
proud to work in earnest specifically with IBM to create a innovative fuel cell system with the ThinkPad design, the industry standard in
business computing," said Mitsuru Homma, Group Executive of SANYO's Power Solutions Group. "This is quite a new concept that
utilizes both micro fuel cells and rechargeable batteries. This hybrid system could enable the user to efficiently operate IBM's ThinkPad
notebooks for a longer time compared to systems with only a fuel cell whilealso providing the convenience of an AC cordless
