PROBLEM TO BE SOLVED: To suppress variation in the voltage of each solid oxide fuel cell stack.SOLUTION: The solid oxide fuel cell system includes a plurality of solid oxide fuel cell stacks 1-A, 1-B, 1-C, 1-D each formed by laminating planar solid oxide fuel cell and a separator alternately, steam reformers 3-A, 3-B, 3-C, 3-D provided in each solid oxide fuel cell stack and supplying fuel gas, while steam reforming, to the solid oxide fuel cell stacks 1-A, 1-B, 1-C, 1-D, a mass flow controller 2 for regulating the flow rate of fuel gas being supplied to all steam reformers 3-A, 3-B, 3-C, 3-D, and a control unit 6 for regulating the flow rate of pure water used for steam reforming so that the voltages of the solid oxide fuel cell stacks 1-A, 1-B, 1-C, 1-D are equalized, for each solid oxide fuel cell stack. |
