PROBLEM TO BE SOLVED: To enhance follow-up capability to FC output power variation. SOLUTION: This evaporator temperature control device is equipped with an evaporator to which fuel and water are supplied and exhaust gas from a fuel cell is made to flow; a control valve 26 controlling exhaust gas amount flowing in the evaporator 21 from the fuel cell 25; a controller 27 detecting the temperature of a combustion part of the evaporator 21 and controlling the temperature of the combustion part; and a reformer 29 connected to the evaporator 21 and the fuel cell 25. The opening of the control valve 26 is found based on the feedback control with a temperature detecting value in the combustion part of the evaporator 21, the output current of the fuel cell 25 is measured, and the residual hydrogen amount in the exhaust gas from the fuel cell is estimated from the current measuring value to correct the opening of the control valve 26. |
