A laminate which allows to obtain an organic thin-film solar cell having excellent output characteristics and transparency is provided. The laminate as above has a titanium oxide layer that is disposed on the member serving as a light-transmissive electrode layer and serves as an electron transport layer. The titanium oxide layer has a thickness of not less than 1.0 nm and not more than 200.0 nm. The titanium oxide layer contains indium oxide and metallic indium, InOx/Ti is not less than 0.50 and not more than 20.00 in atomic ratio, and InM/Ti is less than 0.100 in atomic ratio, where an elemental titanium content is represented by Ti, an indium oxide content is represented by InOx, and a metallic indium content is represented by InM.

The present invention pertains to a polycrystalline membrane containing metal nitride particles represented by the general formula MN(where M is a metal element in which the Fermi energy is in a position higher than &#x2212;4.4 eV vs L.V. and x is the range over which a rock salt-type structure can be assumed), in which the crystallite size determined by transmission electron microscopy is 10 nm or less, at least some of the crystallites have rock salt-type structure, and the crystallites exhibit (111) orientation but substantially do not exhibit (100) orientation. The present invention also pertains to a method for manufacturing a polycrystalline membrane, comprising forming, by sputtering, a polycrystalline membrane on a substrate having a temperature of less than 200&#xb0; C., the polycrystalline membrane being represented by the general formula MNand being such that at least some crystallites have a rock salt structure and the crystallites exhibit (111) orientation but essentially do not exhibit (100) orientation. The present invention provides a hydrogen-permeable TiNmicroparticle membrane exhibiting a higher mixed hydride ion (H)-electron conduction.

The present invention relates to a proton ceramic fuel cell which has a hydrogen-permeable film as an anode and in which an electrolyte material is BaZrCeYO(x=0.1 to 0.8, z=0.1 to 0.25, x+z&#x2264;1.0) (BZCY). An electron-conducting oxide thin film having a film thickness of 1-100 nm is present between a cathode and an electrolyte comprising the material. The present invention also relates to a method for producing a proton ceramic fuel cell having a hydrogen-permeable film as an anode. The method comprises forming a thin film having a thickness of 1-100 nm between a cathode and an electrolyte comprising BZCY, the thin film comprising an electron-conducting oxide. The present invention provides a novel means for improving the output of a PCFC in which BZCY is used in an electrolyte material, and provides a PCFC having an output that exceeds a benchmark of 0.5 W cmat 500&#xb0; C.
