A couple of the reasons for the arguably practical use of hydrogen fuel cells has been safety and storage.
"Researchers at the University of Illinois at Urbana-Champaign have developed porous support materials that can withstand the rigors of high-temperature reforming of hydrocarbon fuels."
Paul Kenis, a professor of chemical and biomolecular engineering at Illinois states, "These novel materials show great promise for the on-demand reforming of hydrocarbons such as diesel fuel into hydrogen for portable power sources," which hopefully can lead, again, to a practical use and subsequent solution for today's fuel and energy needs.
