固体酸化物型燃料電池及び空気極材料
Document Type and Number:
Japanese Patent JP5767743
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a solid oxide type fuel battery and an air electrode material which enable the suppression of the reduction in output.SOLUTION: A solid oxide type fuel battery 10 comprises: a fuel electrode 20; an air electrode 50; and a solid electrolytic layer 30. The air electrode 50 includes a main phase including a perovskite complex oxide expressed by the general formula ABO, and a secondary phase including a perovskite complex oxide expressed by the general formula ABO(n=1,2,3). The perovskite complex oxides forming the main phase and the secondary phase respectively include at least La at A sites, and at least Ni, Cu and Fe at B sites.
