Title:
INTER-CONNECTOR MATERIAL
Document Type and Number:
Japanese Patent JP3241306
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an inter-connector material for solid electrolyte type electrochemical cell.
SOLUTION: Y2O3-stabilized ZrO2, made of lanthanum chromite material and expressed by formulas (La1-xSrx) (Cr1-y-zTiyCoz)O3 (where 0.1≤x≤0.2, 0.01≤y≤0.1, 0.01≤z≤0.05), (La1-x'Srx') (Cr1-y'-z'Tiy'Niz')O3 (where 0.1≤x'≤0.2, 0.01≤y'≤0.05, 0.01≤z'≤0.08) or (La1-x"Srx") (Cr1-y"-z"Tiy"Fez")O3 (where 0.1≤x"≤0.2, 0.01≤y"≤0.05, 0.01≤z"≤0.05) is used as solid electrolyte. That is, Sr is substituted for one part of La of lanthanum chromite (LaCrO3), and furthermore Ti and Co, Ti and Ni, or Ti and Fe are substituted for one part of Cr so that expansion in a high-temperature reducing atmosphere can be prevented, and conductivity and a coefficient of thermal expansion can be maintained at high values.
