April 29, 2005 IBM and SANYO Electric have demonstrated 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. The SANYO system does not require altering the standard ThinkPad notebook design.
