Hydrogen-producing assemblies, fuel cell systems including the same, methods of producing hydrogen gas, and methods of powering an energy-consuming device. Hydrogen-producing assemblies may include a monolithic body that defines at least a reforming conduit, and in some embodiments a plurality of reforming conduits, in which a feed stream is catalyzed into a reformate gas stream containing hydrogen gas, and a burner conduit, in which a fuel-air stream is combusted. The monolithic body is constructed to conduct heat generated by the exothermic reaction of the combustion from the burner conduit to the reformer conduit. In some hydrogen-producing assemblies, the monolithic body further defines a vaporizing conduit, in which liquid portions of the feed stream are vaporized prior to being delivered to the reformer conduit, and the monolithic body may be constructed to conduct heat from the burner conduit to the vaporizing conduit.

1. A method of producing hydrogen gas, the method comprising: delivering a fuel-air stream to a burner conduit extending through and defined by a heat conductive body;catalyzing, by a combustion catalyst disposed within the burner conduit, combustion of the fuel-air stream in the burner conduit to produce an exhaust stream;delivering a feed stream to a vaporizing region defined by the heat conductive body;vaporizing the feed stream in the vaporizing region to produce a vaporized feed stream;delivering the vaporized feed stream to a reforming conduit extending through and defined by the heat conductive body and adjacent the burner conduit, wherein the heat conductive body extends between the burner conduit and the reforming conduit, and surrounds the burner conduit and the reforming conduit;catalyzing, by a reforming catalyst in the reforming conduit, production of a reformate gas stream containing hydrogen gas from the feed stream;conducting, through the heat conductive body, heat generated by the combustion of the fuel-air stream to the reforming conduit to maintain the reforming catalyst within a reforming temperature range;conducting, through the heat conductive body, heat generated by the combustion of the fuel-air stream to the vaporizing region to support vaporization of the feed stream; andwherein catalyzing by a combustion catalyst disposed within the burner conduit includes: catalyzing, by the combustion catalyst disposed within the burner conduit only in a portion of the burner conduit adjacent to an exhaust outlet of the burner conduit, ignition of the fuel-air stream in the burner conduit; andsupporting combustion of the fuel-air stream in a combustion region of the burner conduit to produce an exhaust stream. 2. The method of claim 1, wherein the reforming conduit includes a plurality of reforming conduits, and further wherein delivering the vaporized feed stream includes delivering the vaporized feed stream to each of the plurality of reforming conduits. 3. The method of claim 1, wherein the burner conduit includes a heat transfer structure that forms a portion of the heat conductive body, wherein the heat transfer structure includes a plurality of heat transfer fins, and further wherein the conducting includes conducting through at least a portion of the plurality of heat transfer fins. 4. The method of claim 1, wherein the burner conduit includes a heat transfer structure, wherein the heat transfer structure includes a plurality of loose packing heat transfer structures, and further wherein the conducting includes conducting through at least a portion of the plurality of loose packing heat transfer structures. 5. The method of claim 1, wherein the vaporizing region forms a portion of the reforming conduit, and further wherein the vaporizing includes vaporizing the feed stream within the reforming conduit. 6. The method of claim 1, wherein the burner conduit includes a heat transfer structure that foams a portion of a monolithic body that extends within the burner conduit. 7. The method of claim 6, wherein the monolithic body forms a portion of the heat conductive body. 8. The method of claim 1, wherein the burner conduit extends longitudinally through the heat conductive body, and the reforming conduit extends longitudinally through the heat conductive body. 9. The method of claim 1, wherein the burner conduit extends along a central longitudinal axis of the heat conductive body, and the reforming conduit is spaced radially from the burner conduit. 10. The method of claim 1, further comprising maintaining the reforming catalyst within the reforming temperature range at least partially from the heat conducted from the burner conduit, wherein the reforming temperature range is 250-315° C. 11. The method of claim 1, wherein the portion of the burner conduit extends for less than one fourth of a length of the burner conduit.
