Hydrogen generation assemblies, hydrogen purification devices, and their components, and methods of manufacturing those assemblies, devices, and components are disclosed. In some embodiments, the assemblies may include a vaporization region with packing material configured to transfer heat from a heated exhaust stream to a liquid-containing feed stream, and/or an insulation base adjacent a combustion region and configured to reduce external temperature of an enclosure. In some embodiments, the assemblies may include a cooling block configured to maintain an igniter assembly in thermal communication with a feed stream conduit, an igniter assembly including a catalytic coating, and/or a fuel stream distribution assembly. In some embodiments, the assemblies may include a heat conducting assembly configured to conduct heat from external heaters to an enclosure portion. In some embodiments, the devices may include frames with membrane support structures and/or may include a microscreen structure configured to prevent intermetallic diffusion.

1. 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 having a bottom portion;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; anda fuel distribution assembly attached to the bottom portion of the enclosure and configured to distribute the at least one fuel stream into the combustion region, the fuel distribution assembly including: a base including at least one passage that is in fluid communication with the combustion region,a mesh assembly supported on the base,a top wall having a perimeter,at least one side wall having a top portion and a bottom portion, the top portion being mounted around the perimeter and the bottom portion being supported on the mesh assembly such that a fuel stream distribution region is formed within the at least one side wall and between the top wall and the mesh assembly,an inlet into the fuel stream distribution region, anda fuel stream conduit fluidly connected to the inlet and configured to receive the at least one fuel stream, wherein the mesh assembly includes at least one pathway for the at least one fuel stream to flow from the fuel stream distribution region to the combustion region. 2. The assembly of claim 1, wherein the mesh assembly extends into the combustion region, the heating assembly further comprising at least one combustion catalyst supported within the combustion region via the mesh assembly, the at least one combustion catalyst configured to combust hydrogen in the presence of oxygen. 3. The assembly of claim 1, wherein the inlet is formed on the top wall and the fuel stream conduit goes through a portion of the enclosure. 4. The assembly of claim 1, wherein the enclosure defines a longitudinal axis, and the fuel stream conduit extends along the longitudinal axis. 5. The assembly of claim 4, wherein the enclosure includes a longitudinal axis, and the fuel stream conduit extends along an axis parallel to but spaced from the longitudinal axis. 6. The assembly of claim 4, wherein at least one of the top wall and the at least one side wall is formed with the enclosure. 7. The assembly of claim 1, wherein the mesh assembly includes at least one layer of mesh. 8. The assembly of claim 1, further comprising 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.
