The steam reforming of hydrous ethanol may be the next source of hydrogen for PEM fuel cells. A discussion of many methods of hydrogen production is presented. Experimentation with operational variables for ethanol steam reforming resulted in optimal conditions of T=500 degrees C, WHSV= 12 hr -1, and just higher than stoichiometric ratios of water to ethanol. WGSR and methane steam reforming on a Ni- based catalyst are also investigated. These data are used to postulate a plausible mechanism for hydrous ethanol steam reforming.
