IBM Japan and Sanyo are teaming up to bring a real fuel cell system to notebook PCs in the near future.
Sanyo 已經先發展出混和式的電池，包括傳統的鋰電池與燃料電池可以供應 8 小時的電量：
Sanyo has already developed a hybrid battery system with both standard lithium ion battery and fuel cell which can be used on existing ThinkPad models. Said system uses a 130cc cartridge, leading to about 8 hours of battery life.
文中最後說，最值得讚賞的是燃料電池的部分可以 Hot-swapping，但最讓人厭惡的是要 2.2kg XD (比 Notebook 還重…)
