ELECTRODE FOR SOLID OXIDE FUEL CELL, AND CELL OF SOLID OXIDE FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide an electrode for a solid oxide fuel cell with its interface resistance lowered.

SOLUTION: The electrode for the solid oxide fuel cell is obtained by molding and calcining powder of compound particles 1 with electron conductive metal oxide 2 and oxide ion conductive metal oxide 3 condensed. In the electrode for a solid oxide fuel cell, a 50% particle size (D50) of a volume reference in a particle size distribution measurement of the powder of compound particles 1 is 0.01-1.3 μm, and a ratio (D75/D25) of the 75% particle size (D75) to the 25% particle size (D25) of the volume reference at the particle size distribution measurement of the powder of compound particles is 1.1-2.2.
