PROBLEM TO BE SOLVED: To enhance power generating efficiency of the whole module by the utilization of heat generated in a cell by arranging a fuel supply pipe in which a reforming catalyst is filled on the inside of a tubular internal reforming type solid electrolyte fuel cell having plural unit cells. SOLUTION: Plural unit cells formed by arranging an air electrode 16 and a fuel electrode 17 on each side of a solid electrolyte film 15 are arranged in a tubular state within a power generating chamber 9 in a power generating system main body 1. Fuel comprising H2 and CO is supplied to a fuel electrode 17 of a solid electrolyte fuel cell through a fuel supply pipe 18 arranged on the inside of the fuel electrode, air is supplied to an air electrode 16 through inlet and outlet pipes 20, 21, and power is generated by combustion of fuel. A catalyst layer 19 comprising a reforming catalyst containing nickel or the like is filled in the fuel supply pipe 18, CH4 and H2 are supplied to the catalyst layer 19, heat generated in the cell is absorbed to convert into H2 and CO by reforming reaction. Deposition of carbon producing by reforming on the electrode is prevented, and heat efficiency and power generating efficiency are enhanced. |
