<P>PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell, a solid oxide fuel cell stack, and a solid oxide fuel cell device. <P>SOLUTION: A solid oxide fuel cell includes solid oxide fuel battery cells 1 that each is provided with a fuel electrode 12 in contact with a fuel gas, an air electrode 13 in contact with an oxidizer gas and a solid electrolyte body 11; and a connector 23 made of ceramic, ensuring the electrical conduction with the cell. The connector includes, as constituents, MgO, SiO<SB POS="POST">2</SB>, Al<SB POS="POST">2</SB>O<SB POS="POST">3</SB>and other oxides, and specifically 50 to 90 mol% of MgO, 2 to 40 mol% of SiO<SB POS="POST">2</SB>, and 1 to 20 mol% of Al<SB POS="POST">2</SB>O<SB POS="POST">3</SB>based on 100 mol% of a total of MgO, SiO<SB POS="POST">2</SB>, Al<SB POS="POST">2</SB>O<SB POS="POST">3</SB>and the other oxides, and the other oxides includes at least one of MnO and TiO<SB POS="POST">2</SB>. <P>COPYRIGHT: (C)2012,JPO&INPIT |
