PROBLEM TO BE SOLVED: To provide a solid oxide type fuel battery system that can suppress local excessive temperature increase of combustor, and can be stably started up without imposing any thermal load on a structure.SOLUTION: A solid oxide type fuel battery system 100 includes a solid oxide type fuel battery 1, a source gas supplier 5 that supplies source gas to the solid oxide type fuel battery, a combustible gas flow path 11 extending from a raw material gas supplier to the anode of the solid oxide type fuel battery, an air supplier 6 for supplying air to the solid oxide type fuel battery, an air flow path 12 extending from the air supplier to the cathode of the solid oxide type fuel battery, a combustor 3 for combusting combustible gas discharged from the anode and air discharged from the cathode, an air heat-exchanger 9 which is provided in the air flow path and exchanges heat between exhaust gas generated by the combustion of the combustor and the air, and a controller 7 for performing control of intermittently supplying raw gas to the combustor and control of supplying air to the combustor under intermittent supply of the raw gas in a start-up process.SELECTED DRAWING: Figure 1 |
