    摘要： The present invention generally relates to conducting materials such as mixed ionically and electrically conducting materials. A variety of materials, material compositions, materials with advantageous ratios of ionically and electrically conducting components, structures including such materials, and the like are provided in accordance with the invention. In one aspect, the invention relates to conducting ceramics for electrochemical systems and, in particular, to mixed ionically and electrically conducting ceramics which can be used, for example, for electrochemical systems and, in particular, to mixed ionically and electrically conducting ceramics which can be used, for example, for hydrogen gas generation from a gasified hydrocarbon stream. One aspect of the invention provides a material comprising a first phase comprising a ceramic ionic conductor, and a second phase comprising a ceramic electrical conductor. An example of such a material is a material comprising ZrO2 doped with Sc2O3 and SrTiO3 doped with Y2O3. Another aspect of the invention provides systems and methods of hydrogen gas generation from a fuel, such as a carbonaceous fuel, using materials such as those described above, for example, present within a membrane in a reactor. In some embodiments, a substantially pure hydrogen stream may be generated through in situ electrolysis. In some cases, a material such as those described above may be used to facilitate ion and/or electron exchange between a first reaction involving a fuel such as a carbonaceous fuel, and a second reaction involving a water-hydrogen conversion reaction (i.e., where water is reduced to produce hydrogen gas). In other aspects, the invention provides systems and methods for producing power from a fuel source, such as a carbonaceous fuel source.
