PURPOSE: To make a fuel cell power generating system compact and reduce cost by controlling a flow rate control valve by a measuring value of a temperature sensor to control the temperature of a combustion chamber. CONSTITUTION: In a fuel cell power generating system, the minimum output of a reformer 10 is set to around 30%. When the output of a fuel cell 20 is less than 30%, the flow rate of a fuel gas 1 is made 30% of a rated output, and the flow rate of nitrogen gas 51 is controlled with a flow rate control valve 52 so that the temperature of a combustion chamber Co becomes specified value, for example temperature in 30% output. An exhaust gas processing device and its running cost are made unnecessary, and the compact fuel cell is obtained at low cost. |
