ELECTRODE FOR SOLID ELECTROLYTE, ITS MANUFACTURING METHOD, ITS USING METHOD, SOLID ELECTROLYTE TYPE OXYGEN SENSOR, AND EXHAUST GAS SENSOR

摘要

PROBLEM TO BE SOLVED: To provide an electrode for a solid electrolyte which is chemically stable and sensitive to oxygen ion conductivity, making an oxygen sensor or a fuel cell operable in a wide temperature range by increasing the contact area of particles by forming a thin film fine structure in which ruthenium oxide fine particles and stabilized zirconia fine particles are uniformly dispersed.

SOLUTION: The electrode for the solid electrolyte is formed in such a way that ruthenium oxide-yttrium stabilized zirconia composite electrode having thin film fine structure comprising fine particles having almost uniform particle size of an average particle size of 1 nm to 100 μm, and in which the yttrium stabilized zirconia phase and the ruthenium oxide phase are uniformly dispersed each other on the particle level is formed on the surface of an oxygen ion conductive solid electrolyte substrate made of zirconium oxide containing a stabilizer.
