Abstract:
1. A hydrogen-generation assembly, comprising: a fuel processing system having a hydrogen-producing region adapted to receive a feed stream and to produce a mixed gas stream containing hydrogen gas and other gases therefrom, wherein hydrogen gas forms a majority component of the mixed gas stream; a pressure swing adsorption (PSA) assembly adapted to receive and separate during a PSA cycle at least a portion of the mixed gas stream into a product stream and a byproduct stream, wherein the product stream contains a greater concentration of hydrogen gas than the mixed gas stream and has a reduced concentration of the other gases than the mixed gas stream, wherein the byproduct stream containing byproduct gas contains at least a substantial portion of the other gases, and further wherein the PSA assembly is adapted to intermittently discharge the byproduct stream during the PSA cycle; a pressure-driven combustion stream supply system adapted to receive the byproduct stream from the PSA assembly and to continuously supply, during the PSA cycle, a combustion fuel stream containing the byproduct gas and having at least a predetermined threshold fuel value to a downstream component of a fuel processing system, the combustion stream supply system comprising:
