FLAT TUBULAR OR PLATE TYPE SOLID OXIDE FUEL CELL

摘要

The present invention relates to a solid oxide fuel cell comprising: a plurality of unit cells; and connection layers among the plurality of unit cells. Each unit cell includes a negative pole; a positive pole; and a solid electrolyte between the negative pole and the positive pole. Each connection layer includes i) a first layer comprising La-ferrite containing one or more selected from a group consisting of Sr, Ca and Ba; and ii) a second layer comprising La-ferrite containing one or more selected from a group consisting of Sr, Ca and Ba, and one or more cerias selected from a group consisting of Gd-doped ceria (GDC), La-doped ceria (LDC) and Sm-doped ceria (SDC), wherein the first layer contacts the positive pole of each unit cell and the second layer contacts the negative pole of each unit cell.
