<P>PROBLEM TO BE SOLVED: To provide a Fe-Cr-Al-based heat resistant alloy for an interconnector material used in a solid oxide type fuel cell, which has solved a problem originating from Cr<SB>2</SB>O<SB>3</SB>occurring in an interface between an air pole and an electrolyte, and also to provide the solid oxide type fuel cell using it. <P>SOLUTION: The Fe-Cr-Al-based heat resistant alloy for the interconnector of the solid oxide type fuel cell comprises the following elements so as to satisfy 0 wt.% <C≤ 0.2 wt.%, 0 wt.% <Si≤ 0.05 wt.%, 0 wt.% <Mn≤ 0.47 wt.%, 15 wt.%≤Cr≤22 wt.%, 1.5 wt.% ≤Al≤ 4 wt.%, 0 wt.% <M≤ 0.05 wt.% (M is one or two elements selected from Y and Gd), and the balance Fe with unavoidable impurities. The solid oxide type fuel cell uses the alloy. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
