ABSTRACT:
Hydrogen-producing fuel processing assemblies and fuel cell systems with at least one temperature-responsive valve assembly, and methods for feedback regulation of the hydrogen-producing region. The temperature-responsive valve assembly responds automatically to the temperature of a gas stream of interest to regulate the flow of a subject gas stream therethrough. In some embodiments, these streams are the same streams, while in others, they are different streams. The streams may include at least the reformate stream from a hydrogen-producing region of the fuel processing assembly, the byproduct stream from a purification region, and the product gas stream from the purification region. In some embodiments, the subject gas stream may be the byproduct stream, which is in fluid communication for delivery as a combustible fuel stream for a burner or other heating assembly that produces an exhaust stream to heat the hydrogen-producing region of the fuel processing assembly.
