PROBLEM TO BE SOLVED : To improve the conductivity of an interconnector made of MTiO3 ceramic (M represents at least one selected from Mg, Ca, Sr, and Ba) and to enhance efficiency of a cell.
SOLUTION : The solid oxide fuel cell is equipped with : a plurality of cells 6 interconnectors 7 for electrically connecting one adjacent cell to other cell. The cell 6 is equipped with an electrolyte membrane 4, an air electrode 5, and a fuel electrode 3. The interconnector 7 contains material represented by (M1-xDx)TiO3. M is selected from the group comprising Mg, Ca, Sr, and Ba. D is selected from the group comprising rare earth elements, Al, and Cr. X is 0
