Successful deployment of man-portable, low-temperature proton exchange membrane (PEM) fuel cells depends on finding a suitable hydrogen fuel that is easily stored and transported, inexpensive, readily available, safe, and practical for use in light and compact vessels. Because storage of hydrogen as a compressed gas in metal cylinders is inefficient and heavy, many alternative methods to store hydrogen have been investigated. This report lists several technologies for the storage and generation of hydrogen and provides brief descriptions.
