PROBLEM TO BE SOLVED: To provide a highly reliable fuel cell system in which an external reforming of a fuel gas is not necessary and a coking of the fuel gas is not generated in the interior of the fuel cell. SOLUTION: A container having 3 chambers, the first chamber is the first supply chamber 8 which supplies the first gas 1, the second chamber is a discharge chamber 9 which exhausts the first gas 1, the third chamber is the second supply chamber 4 which supplies the second gas 2, and cell tubes of the fuel cell with a double-tube structure of an inner tube 12 and an outer tube 3 in which the fuel cell is formed are provided, the first end part which is one end part of the outer tube 3 of the cell tubes of the fuel cell are opened and joined to the discharge chamber 9, the second end part which is another end part of the outer tube 3 is extended to an inside of the second supply chamber 4 and occluded, the third end part which is one end part of the inner tube 12 of the cell tubes of the fuel cell are opened and joined to the first supply chamber 8, the fourth end part which is another end part of the inner tube 12 is extended to the vicinity of the second end part, and a catalyst 11 to reform the first gas 1 is formed on the inner wall face of the inner tube 12 so as to extend from the third end part to the fourth end part. |
