Title:
導電体および固体酸化物形燃料電池セルならびにセルスタック、燃料電池
Document Type and Number:
Japanese Patent JP5748584
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a conductor high in conductivity at high temperature and a solid oxide fuel battery cell, a cell stack, and a fuel battery.SOLUTION: A conductor has a composition, based of mole ratios, represented as La(NiCuFe)O, where x, y and z satisfy 0.5 to 0.6, 0.01 to 0.1 and 0.95 to 1.05, respectively. The conductor preferably comprises a perovskite composite oxide containing La at the A-site and Ni, Cu and Fe at the B-site and having general formula represented as ABO. Thereby, conductivity at high temperatures can be increased. The conductor can be used as an oxide electrode or a collector of a fuel battery cell.
