Fuel Cell Forklift
Although Nissan has been working on fuel cell-powered road vehicles, mostly in Japan, they haven't garnered nearly the attention that Honda, GM, DaimlerChrysler and Ford have. There have been plenty of arguments for and against fuel cells here and elsewhere. However, closed vertical applications like factories are probably the best short term application for fuel cell technology because of the localized fueling infrastructure.
