POSITIVE ELECTRODE MATERIAL FOR FUEL CELL, POSITIVE ELECTRODE FOR FUEL CELL INCLUDING THE SAME, AND SOLID OXIDE FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide a positive electrode material for fuel cell, positive electrode for fuel cell including the same, and solid oxide fuel cell.

SOLUTION: The positive electrode material for fuel cell comprises a perovskite metal oxide and ceria family metal oxide that is doped by at least two types of lanthanoid heterogeneous elements different from each other and that has an average ion radius of the lanthanoid heterogeneous element of 0.90-1.02 Å.
