A porous body includes a framework having a three-dimensional network structure, the framework having a body including crystal grains including nickel and cobalt as constituent elements, the cobalt having a proportion in mass of 0.2 or more and 0.8 or less with respect to a total mass of the nickel and the cobalt, the crystal grains having a shorter grain diameter of 2 &#x3bc;m or more, as determined in a first observed image obtained by observing the body of the framework in cross section at a magnification of 200 times.

A positive-electrode bodyis prepared that includes a positive-electrode active-material layerincluding a powder-molded body, and a positive-electrode-side solid-electrolyte layer (PSE layer)that is amorphous and formed on the positive-electrode active-material layerby a vapor-phase process. A negative-electrode bodyis prepared that includes a negative-electrode active-material layerincluding a powder-molded body, and a negative-electrode-side solid-electrolyte layer (NSE layer)that is amorphous and formed on the negative-electrode active-material layerby a vapor-phase process. The positive-electrode bodyand the negative-electrode bodyare bonded together by subjecting the electrode bodiesandbeing arranged such that the solid-electrolyte layersandof the electrode bodiesandare in contact with each other, to a heat treatment under application of a pressure to crystallize the PSE layerand the NSE layer

A hydrogen-permeable structure is disclosed, which includes a hydrogen-permeable base in which a fluctuation range of a d value by X-ray analysis measurement is at most 0.05% in a region within 2 &#x3bc;m deep from a surface, and an oxide proton conductive film formed on a surface thereof. The disclosure also relates to a method of manufacturing the hydrogen-permeable structure and a fuel cell using the hydrogen-permeable structure.

A lithium battery includes a substrate, a positive electrode layer, a negative electrode layer, and a sulfide solid electrolyte layer disposed between the positive electrode layer and the negative electrode layer, the positive electrode layer, the negative electrode layer, and the sulfide solid electrolyte layer being provided on the substrate. In this lithium battery, the positive electrode layer is formed by a vapor-phase deposition method, and a buffer layer that suppresses nonuniformity of distribution of lithium ions near the interface between the positive electrode layer and the sulfide solid electrolyte layer is provided between the positive electrode layer and the sulfide solid electrolyte layer. As the buffer layer, a lithium-ion conductive oxide, in particular, LiLaTiO(x=0.1 to 0.5), LiLaZrO(&#x2212;5&#x2266;x&#x2266;3, preferably &#x2212;2&#x2266;x&#x2266;2), or LiNbOis preferably used.
