Abstract
Hydrogen-producing fuel processing assemblies for producing hydrogen gas. The assemblies include a catalyst chamber, a heat source adapted to heat the catalyst chamber, a hydrogen-producing region within the catalyst chamber adapted to produce hydrogen gas from a feed stream, and a conductive guide structure within the catalyst chamber adapted to conduct and distribute heat from the heat source within the hydrogen-producing region and to direct fluid through the hydrogen-producing region. In some embodiments, the conductive guide structure includes a helical member. In some embodiments, the assembly further includes a vaporization region within the catalyst chamber. In some embodiments, the fuel processing assembly is adapted to produce hydrogen gas via a steam reforming or other endothermic reaction.
