CONNECTING MATERIAL FOR A PIPE-SHAPED SOLID OXIDE FUEL CELL, AND PIPE-SHAPED SOLID OXIDE FUEL CELL STACK INCLUDING SAME

Disclosed is a connector for a solid oxide fuel cell, which electrically connects tubular solid oxide fuel cells to each other. The connector includes a conductive body part having a first electrode contact groove and a second electrode contact groove. A first electrode contact part is formed on the top surface of the body part to receive at least a portion of an exposed first electrode portion and second electrode portion of a first solid oxide fuel cell, and is electrically connected to the first electrode of the first solid oxide fuel cell. A second electrode contact part is formed at the bottom surface of the body part so as to receive at least a portion of exposed first electrode portion and second electrode portion of a second solid oxide fuel cell, and is electrically connected to the second electrode of the second solid oxide fuel cell.
