Abstract
Hydrogen generation assemblies, hydrogen purification devices, and their components, and methods of manufacturing those assemblies, devices, and components are disclosed. In some embodiments, the devices may include an insulation base having insulating material and at least one passage that extends through the insulating material. In some embodiments, the at least one passage may be in fluid communication with a combustion region.

A steam reforming hydrogen generation assembly configured to receive at least one feed stream and generate a reformate stream containing hydrogen gas as a majority component and other gases, comprising:
- an enclosure;
- a hydrogen-producing region contained within the enclosure and including a reforming catalyst, the hydrogen-producing region being configured to produce, via a steam reforming reaction, the reformate stream from the at least one feed stream;
- a heating assembly configured to receive at least one air stream and at least one fuel stream and to combust the at least one fuel stream within a combustion region contained within the enclosure producing a heated exhaust stream for heating at least the hydrogen-producing region to at least a minimum hydrogen-producing temperature;
- and
- an insulation base configured to reduce external temperature of the enclosure, the insulation base being adjacent to the combustion region, wherein the enclosure is supported on the insulation base and the insulation base includes insulating material and at least one passage that extends through the insulating material, the at least one passage being in fluid communication with the combustion region, wherein the insulation base further includes at least one cavity within the insulating material, and wherein the at least one cavity is (a) sized to at least partially receive an air blower configured to produce at least a portion of the at least one air stream and (b) in fluid communication with the at least one passage.
A steam reforming hydrogen generation assembly configured to receive at least one feed stream and generate a reformate stream containing hydrogen gas as a majority component and other gases, comprising:
- an enclosure;
- a hydrogen-producing region contained within the enclosure and including a reforming catalyst, the hydrogen-producing region being configured to produce, via a steam reforming reaction, the reformate stream from the at least one feed stream;
- a heating assembly configured to receive at least one air stream and at least one fuel stream and to combust the at least one fuel stream within a combustion region contained within the enclosure producing a heated exhaust stream for heating at least the hydrogen-producing region to at least a minimum hydrogen-producing temperature;
- and
- an insulation base configured to reduce external temperature of the enclosure, the insulation base being adjacent to the combustion region, wherein the enclosure is supported on the insulation base and the insulation base includes insulating material and at least one passage that extends through the insulating material, the at least one passage being in fluid communication with the combustion region, wherein the heating assembly includes an igniter assembly configured to ignite a fuel stream, the igniter assembly including an igniter element having a catalytically active coating configured to combust hydrogen in the presence of oxygen.
A steam reforming hydrogen generation assembly configured to receive at least one feed stream and generate a reformate stream containing hydrogen gas as a majority component and other gases, comprising:
- an enclosure;
- a hydrogen-producing region contained within the enclosure and including a reforming catalyst, the hydrogen-producing region being configured to produce, via a steam reforming reaction, the reformate stream from the at least one feed stream;
- a heating assembly configured to receive at least one air stream and at least one fuel stream and to combust the at least one fuel stream within a combustion region contained within the enclosure producing a heated exhaust stream for heating at least the hydrogen-producing region to at least a minimum hydrogen-producing temperature;
- an insulation base configured to reduce external temperature of the enclosure, the insulation base being adjacent to the combustion region, wherein the enclosure is supported on the insulation base and the insulation base includes insulating material and at least one passage that extends through the insulating material, the at least one passage being in fluid communication with the combustion region;
- and
- a heat conducting assembly external to the enclosure and attached to at least a portion of the enclosure, the heat conducting assembly being configured to conduct heat from one or more external heaters attached to the heat conducting assembly to the at least a portion of the enclosure.
