PROBLEM TO BE SOLVED: To reduce thermal stress of a fuel cell tube and provide appropriate correspondence to a temperature change during operation in a cartridge structure. SOLUTION: The cartridge structure is provided with a feeding chamber 8 feeding fuel gas 1, a discharging chamber 9 provided away from the feeding chamber 8 and discharging the fuel gas 1, an oxidizer feeding part 4 provided between the feeding chamber 8 and the discharging chamber 9 and feeding oxidizer gas 2, the fuel cell cell tube 3 opened and joined to the feeding chamber 8 by a first end part which is a one end part, opened and joined to a discharge chamber 9 by a second end part which is another end part, and formed with a fuel cell in an outside face of a substrate tube, and frame supports 13 and 15 joined to the feeding chamber 8 by a third end part which is a one end part, joined to the discharging chamber 9 by a fourth end part which is another end part, and having a coefficient of thermal expansion substantially equal to a coefficient of thermal expansion of the fuel cell cell tube 3. |
