Abstract:
PROBLEM TO BE SOLVED: To create a new noble-metal nano particle having shape, size and arrangement which can be used for a catalyst, an electrode, etc. SOLUTION: The micell having a semi-cylindrical sectional shape and formed like a bar is formed on a carrier substrate in a self-creation fashion and fixed. Noble-metal ions are added and dispersed in the micell. The micell and the noble-metal ions are compounded, then, reacted with a reducing agent for promoting a reduction reaction of the noble metal in the fixed micell as the reaction field for growing the single crystalnoble-metal super-thin film nano particle on the carrier substrate using the fixed micell of the shape as a mold.

Abstract:
PURPOSE:To decrease electrode material to reduce cost by impregnating organic metal salt solution such as octylate solution in a porous substrate comprising, for example, alumina or silica, and forming an oxide electrode by oxidation- thermal decomposition of the organic metal salt. CONSTITUTION:Organic metal salt solution such as nickel octylate solution is impregnated in a porous substrate 6 comprising, for example, alumina or silica, and oxidation-thermal decomposition is conducted to deposite nickel oxide on the porous substrate 6. Thereby, a porous oxide electrode 7 for a solid electrolyte fuel cell is formed. The oxide electrode 7 has high conductivity suitable for electrode material, and is easily formed on the surface of a porous substrate. By this process, since sandwich construction of an electrode, an electrolyte, and an electrode is easily formed, electrode material is reduced and cost is also decreased.
