PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell system facilitating a simple control.SOLUTION: The solid oxide fuel cell system has a cell stack 10 including plural cells, connected to each other in series, each having an anode and a cathode. The solid oxide fuel cell system includes: a solid oxide fuel cell 12 that generates the power using a fuel gas 24 supplied to the anode and air 20 supplied to the cathode; a temperature adjustment mechanism 14 that adjusts the temperature on the cell stack; and a control unit 18 that controls the temperature adjustment mechanism to adjust the temperature on the cell stack so that the voltage output from the cell stack is constantly maintained at preset current density. The temperature on the cell stack is controlled to increase as integrated operation time of the solid oxide fuel cells increases. |
