| titleOfInvention | Rare earth solid solution ceria polycrystal with high oxide ion conductivity and transport number |
| abstract | A rare earth solid solution ceria polycrystal which provides high oxide ion conductivity and oxide ion transport number under an oxygen partial pressure of 1 × 10 −30 to 1 × 10 −15 atm at an operating temperature of 800 ° C. or less of a solid oxide fuel cell. And to provide the polycrystal as a fuel cell electrolyte. A composite oxalate is synthesized from a water-soluble salt of a rare earth element of ytterbium, yttrium, gadolinium, samarium, neodymium or lanthanum and a water-soluble salt of cerium by a coprecipitation method. This is thermally decomposed to obtain a high-purity ceria powder in which the rare earth element is solid-dissolved in an amount of 10 mol to 30 mol%. After molding this powder, it is sintered at 1200 ° C. or higher and densified to a relative density of 96% or higher. No second phase was observed in the structure of the sintered body, and the added rare earth element was uniformly distributed in the grains and at the grain boundaries. It was shown that high purity rare earth solid solution ceria having the above structure has high oxide ion conductivity and high oxide ion transport number. [Selection diagram] FIG. |
