<P>PROBLEM TO BE SOLVED: To provide an interconnector which contains no element that degrades battery performance and secures both low reduction expansion nature and high conductivity. <P>SOLUTION: The composition inclination type interconnector is configured so that a reduction expansion rate rises or drops stepwise from one to other facing surfaces of a cell. It is formed from perovskite oxide represented by a general formula Ln<SB>1-x</SB>Ae<SB>x</SB>MO<SB>3-δ</SB>(where, Ln is at least one selected from lanthanoid, Ae is one or more kinds selected from a group comprising Sr, Ba, and Ca, M is one or more kinds selected from a group comprising Ti, Zr, Al, Ga, Nb, Ta, Fe, Co, Ni, Cu, Mn, Mg, Rh, Pd, Pt, and Au, and 0≤x≤1). The composition of perovskite oxide differs from each other for each portion of different reduction expansion rate in stepwise manner. <P>COPYRIGHT: (C)2010,JPO&INPIT |
