  "textContent": "Provided is a fuel cell device improved for operating conditions during a partial load operation. The fuel cell device comprises a cell stack formed by electrically connecting fuel cells for generating power by fuel gas and oxygen-containing gas; a fuel gas supply unit for supplying the fuel gas to the fuel cells; a power adjustment unit for adjusting the amount of current that is supplied to an external load, said current being generated by the fuel cells; and a controller for controlling the fuel gas supply unit and the power adjustment unit. The controller adjusts, during the partial load operation of the fuel cell device and when the fuel gas supplied to the cell stack, the fuel gas supply unit and the power adjustment unit so that a relationship between a fuel utilization rate of the cell stack and the amount of power generated by the cell stack can be nonlinear. Thus, in operation control of the fuel cell device, the partial load operation can be efficiently performed.",
