摘要： A system includes an electrochemically functional membrane, and a support structure constructed and arranged so as to support the membrane while leaving within the membrane a chemically active area having an area utilization of at least about 50%. In some embodiments, the support structure may include a plurality of grids that are sized and shaped so that the contact area between the grids and the membrane is reduced to less than about 40%. In some embodiments, the support structure may include aerogels, for example PVA-reinforced CNT aerogels having a conductivity that is increased by pyrolysis. The system may be a gas separation system; a gas production system; a gas purification system; or an energy generation system such as an SOFC.

摘要： A method comprises creating an electrode by depositing alternating first and second layers on a substrate, and using the electrode to make a solid oxide fuel cell. The first layer comprises a metal, and the second layer comprises a non-metal, for example a ceramic material. The substrate may be moved between a first region containing the metal and substantially free of the non-metal, and a second region containing the non-metal and substantially free of the metal. The composition of the metal and/or the non-metal may be varied along the thickness of the layers. The deposited layers may be heated. A fuel cell may have a fuel cell electrode that comprises a substrate, and alternating first and second layers deposited on the substrate, where the first layer includes a metal and the second layer includes a non-metal. The fuel cell may be a solid oxide fuel cell.
