PURPOSE:To obtain a raw material for a solid electrolyte by sintering only once. CONSTITUTION:As starting raw materials, LaF3 with SrF2, BaF2. or CaF2 powder is weighed in 95:5 mole ratio, mixed in a prescribed period using a shaker mixer, and the resulting mixed powder is sintered. The sintered body is pulverized and the particle size is adjusted to give a solid electrolyte powder for plasma spray. The powder is plasma-sprayed on a fuel electrode 3 in order to form a solid electrolyte thin film 4 for a single cell of a fuel cell. An oxygen electrode 5 is formed on the solid electrolyte thin film 4. |
