Hydrogen-producing fuel processing systems, hydrogen purification membranes, hydrogen purification devices, fuel processing and fuel cell systems that include hydrogen purification devices, and methods for operating the same. In some embodiments, operation of the fuel processing system is initiated
Hydrogen-producing fuel processing systems, hydrogen purification membranes, hydrogen purification devices, fuel processing and fuel cell systems that include hydrogen purification devices, and methods for operating the same. In some embodiments, operation of the fuel processing system is initiated by heating at least the reforming region of the fuel processing system to at least a selected hydrogen-producing operating temperature. In some embodiments, an electric heater is utilized to perform this initial heating. In some embodiments, use of the electric heater is discontinued after startup, and a burner or other combustion-based heating assembly combusts a fuel to heat at least the hydrogen producing region, such as due to the reforming region utilizing an endothermic catalytic reaction to produce hydrogen gas.

The invention claimed is: 1. A method for starting operation of a hydrogen-producing fuel cell system, the method comprising: electrically heating, during a startup period, a reforming region containing a catalyst to a selected hydrogen-producing operating temperature of at least 200° C.; wherein when heated to the selected hydrogen-producing operating temperature, the catalyst is adapted to catalyze, via an endothermic reaction, the formation of a mixed gas stream containing hydrogen gas as a majority component and other gases from a feed stream delivered thereto; ceasing the electrically heating; delivering a feed stream containing at least water and a carbon-containing feedstock to the reforming region; producing the mixed gas stream from the feed stream; separating the mixed gas stream into a product hydrogen stream, which contains hydrogen gas of greater purity than the mixed gas stream, and a byproduct stream, which contains at least a substantial portion of the other gases; combusting at least a portion of the byproduct stream to produce a heated exhaust stream; heating the reforming region with the heated exhaust stream; delivering at least a portion of the product hydrogen stream to a fuel cell stack; and producing an electric current with the fuel cell stack from an oxidant and the portion of the product hydrogen stream. 2. The method of claim 1, wherein the electrically heating includes utilizing an electric resistance heater to heat the reforming region. 3. The method of claim 2, wherein the electric resistance heater extends within the reforming region. 4. The method of claim 1, wherein the ceasing the electrically heating includes ceasing the electrical heating after detection that the catalyst has been heated to the selected hydrogen-producing operating temperature. 5. The method of claim 1, wherein the method further comprises pressurizing at least the reforming region to at least 50 psi. 6. The method of claim 1, wherein the combusting further comprises receiving and combusting an exhaust stream from the fuel cell stack to form at least a portion of the heated exhaust stream. 7. The method of claim 1, wherein the separating includes utilizing at least one hydrogen-selective membrane to separate the mixed gas stream into the product hydrogen stream and the byproduct stream, wherein the product hydrogen stream is formed from a portion of the mixed gas stream that passes through the at least one hydrogen-selective membrane and the byproduct stream is formed from a portion of the mixed gas stream that does not pass through the at least one hydrogen-selective membrane. 8. The method of claim 7, wherein the hydrogen-selective membrane is formed from a palladium alloy containing carbon, but no more than 219 ppm carbon. 9. The method of claim 7, wherein the hydrogen-selective membrane is formed from a palladium alloy containing carbon, but no more than 40 ppm carbon. 10.

The method of claim 14, wherein the separating includes utilizing a separation assembly to at least temporarily trap at least a substantial portion of the other gases for subsequent removal in the byproduct stream. 16. The method of claim 1, wherein the method further comprises storing at least a portion of the mixed gas stream. 17. The method of claim 16, wherein the storing includes storing at least a portion of the mixed gas stream in a hydride bed. 18. The method of claim 16, wherein the method further comprises delivering the portion of the mixed gas stream to the fuel cell stack or for use as a combustible fuel to heat at least the reforming region. 19. The method of claim 1, wherein the electrically heating includes electrically heating the reforming region containing the catalyst to a selected hydrogen-producing operating temperature of at least 375° C. 20. The method of claim 2, wherein the electric resistance heater is external to, but in thermal communication with, the reforming region. 21. The method of claim 1, wherein the ceasing the electrical heating includes ceasing the electrical heating before the reforming region begins to produce the mixed gas stream. 22.
