[PROBLEMS] To provide a solid oxide fuel cell system that can be controlled while taking the influence of the volume of water kept in a water tank into consideration and is fully water self-sustainable. [MEANS FOR SOLVING PROBLEMS] The solid oxide fuel cell system comprises a fuel cell (21) provided with a reforming part (22), a gas-water supply system (10) for supplying a plurality of kinds of gases and water to the reforming part (22), and a water tank (50) for storing water. The gas-water supply system (10) comprises a reforming gas supply part (12) for supplying a reforming gas, an oxygen- containing gas supply part (13) for supplying an oxygen-containing gas, and a water supply part (14) for supplying water from the water tank (50). A control unit (15) is further provided for controlling whether, based on a signal from a stored water volume sensor (51) which detects the volume of water kept in the water tank (50) for carrying out a reforming reaction in the reforming part (22), switching between an oxygen-containing gas supply part (13) and the water supply part (14) is carried out, or both the supply parts (13,14) are used in combination. |
