PROBLEM TO BE SOLVED: To eliminate damage at a burning time, and lessen deformation by inserting a ceramics bar or tube into a through hole provided in a cylindrical solid electrolyte fuel cell, and supporting the inserted ceramics bar or tube through a support base at the burning time. SOLUTION: A burning supporting opening portion 2 in the end portion of a cylindrical solid electrolyte fuel cell 1, a ceramics-made tube or bar 3 is inserted into the burning supporting opening portion 2, and the ceramics-made tube or bar 3 is supported by a burning time support base 4 at a burning time. When the diameter of the burning time supporting opening 2 is expressed by (r), the outer diameter of the cylindrical solid electrolyte fuel cell 1, by R, and a distance from the end portion to the burning supporting opening portion 2, by L, a relation in which solid burning is possible is satisfied when r/R is 2/3 or less, and L is 20mm or more. Thereby, damage at a burning time is eliminated, and deformation is lessened. |
