To facilitate that a member on which a cell tube of a fuel cell is mounted is made to be easier to cope with large-sizing of the fuel cell by dividing, downsizing and weight reduction of the member.
This uses a fuel cell system wherein this is provided with cell tubes 8.3 of the fuel cell, which have a double-tube structure composed of the first inner tubes 8 and the first outer tubes 3, and in which a cell of the fuel cell has been formed at the outer face of the first outer tube 3, with the first gas supply tube which has a double-tube structure composed of the second inner tubes 4 and the second outer tubes 5, and in which the first gas 2 is supplied from the second inner tube 4 to the cell tubes 8.3 of the fuel cell and the first exhaust gas 2 from there is discharged from the second outer tube 5, and with the second gas supply chamber 48 to supply the second gas 1 to the cell tubes 8.3 of the fuel cell, and wherein the first end part which is the end part of the first outer tube 3 is opened to and joined with the side face of the second outer tube 5, the second end part which is the other end part of the first outer tube 3 is extended to the inside of the second gas supply chamber 48 and occluded, the third end part which is one end part of the first inner tube 8 is opened to and joined with the side face of the second inner tube 4, and the fourth end part which is the other end part of the first inner tube 8 is extended to the vicinity of the second end part and opened.
