COMPOSITE PARTICLE POWDER AND ITS MANUFACTURING METHOD, ELECTRODE FOR SOLID OXIDE FUEL CELL AND ITS MANUFACTURING METHOD, AND SOLID OXIDE FUEL BATTERY CELL

摘要

PROBLEM TO BE SOLVED: To provide an electrode for a solid oxide fuel cell having a large amount of three-phase interfaces and further, a solid oxide fuel battery cell having a high durability.

SOLUTION: A composite particle powder is obtained by carrying out an atomization thermal decomposition process in which spray liquid containing a raw material metal salt of amorphous metal-oxide precursor of two kinds or more or spray liquid containing metal-oxide particulates of an average particle size of 0.01-0.3 μm and a raw material metal salt of amorphous metal oxide precursor is sprayed in a heating furnace of 300-900°C to obtain the composite particle powder. The electrode for the solid oxide fuel cell is obtained by forming the composite particle powder and then calcining it.
