Provided is a method for easily producing a thin-membrane solid electrolyte body. A molded body () of a first ceramic is prepared, and the molded body () is fired in a first temperature range to prepare a porous body (). A thin membrane-shaped molded body () composed of a second ceramic containing a solid electrolyte is prepared on at least a part of a surface of the porous body (). A dense body () is prepared by firing the thin membrane-shaped molded body (). As a result, a solid electrolyte body () including the porous body () as a support and the dense body () of a thin membrane-shaped electrolyte integrally formed with at least a part of the surface of the porous body (), is produced.

Solid electrolyte, method for producing the same, and secondary battery comprising solid electrolyte

Described herein are solid oxide fuel cells and manufacturing methods thereof. In certain aspects, the solid oxide fuel cells described herein include a plurality of anodes and a plurality of cathodes in which the anodes and cathodes are alternately stacked on each other and have non-overlapping sections in which the anodes and cathodes do not overlap partially. In certain aspects, the plurality of anodes are electrically connected to a first electrode, and the plurality of cathodes are electrically connected to a second electrode. In certain aspects, a solid electrolyte can be included, for example, between the anode and the cathode. In certain aspects, partitioning sections are disposed between each of the cathodes and the first electrode and between each of the anodes and the second electrode.

To provide a method and an apparatus for reforming a hydrocarbon with a prolonged life of an oxygen-permeable membrane and a high recovery rate. The oxygen-permeable membrane absorbs the free energy change, &#x394;G, of a partial oxidation reforming reaction and then converts it into work for oxygen isolation and Joule heat, Q. Here, as seen in Table 1 and FIG., &#x394;G of the partial oxidation reforming reaction is approximately ten times larger than &#x394;H, and further increases as the temperature increases. The generated Joule heat, Q, has to be removed at a high efficiency, and this removal process is achieved by returning a portion of the Joule heat to the system as the entropy change, T&#x394;S, of the partial oxidation reaction itself and by steam reforming using the total energy change, &#x394;H.

It is a composite-type mixed oxygen ion and electronic conductor, in which an oxygen ion conductive phase consists of gadolinium-doped cerium oxide (GDC), an electronic conductive phase consists of spinel-type ferrite (CFO), the particle diameters of both phases are 1 &#x3bc;m or less, respectively, both phases are uniformly mixed mutually, and both phases form respective conductive networks. Both phases have low solid solubility mutually, chemical reactions are not easily caused between both phases, and even if chemical reactions are caused between both phases, different phase to disturb mixed conductivity is not formed. And it has high oxygen permeability, and does not easily cause aged deterioration.
