Hydrogen purification membranes, hydrogen purification devices, and fuel processing and fuel cell systems that include hydrogen purification devices. The hydrogen purification membranes include a metal membrane, which is at least substantially comprised of palladium or a palladium alloy. In some embodiments, the membrane contains trace amounts of carbon, silicon, and/or oxygen. In some embodiments, the membranes form part of a hydrogen purification device that includes an enclosure containing a separation assembly, which is adapted to receive a mixed gas stream containing hydrogen gas and to produce a stream that contains pure or at least substantially pure hydrogen gas therefrom. In some embodiments, the membrane(s) and/or purification device forms a portion of a fuel processor, and in some embodiments, the membrane(s) and/or purification device forms a portion of a fuel processing or fuel cell system.

The process of claim 1 wherein the dye is an acid dye. 3. The process of claim 1 wherein the dye is a premetallized acid dye. 4. The process of claim 1 wherein the dye is a reactive dye. 5. A method for arresting or attenuating ultraviolet induced damage to cationic dyeable nylon fibers, which have been dyed at a pH of about 2.5 or less with an acid dye, a premetallized acid dye or a fiber reactive dye, after installation of a carpet containing said fibers, the process comprising the steps of: subsequent to exposing the fibers of the installed and dyed carpet to fiber damaging amounts of ultraviolet light, applying heat and a neutralizing aqueous solution having a pH of about 7.5 or greater to said fibers in the installed carpet thereby arresting or attenuating ultraviolet induced damage to the nylon fibers of the installed carpet. 6. The process of claim 5 wherein the dye is an acid dye. 7. The process of claim 5 wherein the dye is a premetallized acid dye. 8. The process of claim 5 wherein the dye is a reactive dye. 9. A process for arresting or attenuating ultraviolet induced damage to nylon fibers comprising: dyeing cationic dyeable nylon fibers at a pH of about 6.0 or less with an acid dye, a premetallized acid dye or a reactive dye for a time sufficient to reduce the tenacity of the cationic dyeable nylon fibers; and subsequent to exposing said fibers to fiber damaging amounts of ultraviolet light, applying a neutralizing aqueous solution having a pH of about 7.5 or greater to said fibers and heating the fibers, thereby arresting or attenuating ultraviolet induced damage to said nylon fibers. 10. The process of claim 9 wherein the dye is an acid dye. 11. The process of claim 9 wherein the dye is a premetallized acid dye. 12. The process of claim 9 wherein the dye is a reactive dye. 13. A method for arresting or attenuating ultraviolet induced damage to cationic dyeable nylon fibers, which have been dyed at a pH of about 6.0 or less with an acid dye, a premetallized acid dye or a fiber reactive dye for a time sufficient to reduce the tenacity of the cationic dyeble nylon fibers, after installation of a carpet containing said fibers, the process comprising the steps of: subsequent to exposing the fibers of the installed and dyed carpet to fiber damaging amounts of ultraviolet light, applying heat and a neutralizing aqueous solution having a pH of about 7.5 or greater to said fibers in the installed carpet thereby arresting or attenuating ultraviolet induced damage to the nylon fibers of the installed carpet. 14. The process of claim 13 wherein the dye is an acid dye. 15. The process of claim 13 wherein the dye is a premetallized acid dye. 16. The process of claim 13 wherein the dye is a reactive dye. 17. The process of claim 13 wherein the aqueous solution is applied to the carpet or yarns for a period of at least 5 minutes. e3, Exceptionally Energy Efficient Fan Filter Unit brochure, Envirco Corporation, 1998, 4 total pages.
