1. A desulfurizer-reformer reactor system comprising a desulfurizing material comprising one or more thermally and microstructurally stable metal oxides dispersed on an inert support, and a sulfur-tolerant reforming catalyst material arranged as a gradient assembly,
wherein the desulfurizing material and/or the reforming catalyst material are configured to be regenerable using an oxidation process; the gradient assembly comprising: i) a first chamber containing a nanoporous matrix having dispersed thereon the desulfurizing material, the first chamber being configured for receiving a sulfur-laden fuel mixture, such that the sulfur-laden fuel mixture, when brought into contact with the desulfurizing material, is substantially denuded of sulfur-bearing species in an exothermic reaction; and ii) a second chamber containing a nanoscale high-surface area ceramic support having dispersed thereon the sulfur-tolerant reforming catalyst material, wherein the reforming catalyst material comprises ceria nominally doped with Gd2O3 or ZrO2: the second chamber being configured for receiving the fuel mixture from the first chamber, such that the sulfur-tolerant reforming catalyst material removes additional sulfur in the fuel mixture in an endothermic reaction sufficient to provide a sulfur-free, hydrogen-rich fuel mixture; wherein the first chamber and the second chamber are concentric chambers; and wherein the first chamber containing the desulfurizing material is separated from the second chamber containing the reforming catalyst material by a heat exchangeable metal or alloy.
