What technology developments are needed in order to apply fuel cells in transportation applications?
Probably the most important developments required for transportation applications of fuel cells involve fuel handling and fuel processing. Since the fuel cell considered the primary candidate for transportation applications, the proton exchange membrane (PEM) fuel cell, requires a clean hydrogen fuel, stringent requirements are placed upon the processing of typical transportation fuels like gasoline and methanol. The development of compact, efficient, cost effective and high-purity hydrogen producing reformer technology is a key requirement. Another strategy which could avoid the “on-board” reformation of liquid transportation fuels is the storage and direct use of hydrogen. This approach would require significant advances in the storage of hydrogen which may be accomplished through metal hydride or carbon nano-tube storage of hydrogen, or the development of crash-worthy high-pressure hydrogen storage technology. This approach would also require significant development of hydrogen supp
