PROBLEM TO BE SOLVED: To recover a catalytic reaction of a combustion catalyst in a fuel cell system comprising the combustion catalyst.SOLUTION: A fuel cell system 100 includes: a fuel cell 34 for generating power using a reformed gas generated by a reforming unit 33 and an oxidant gas; a combustion unit 36 for burning, using the oxidant gas, an anode off-gas including a combustible component discharged from the fuel cell 34; a combustion catalyst 28 to which a flue gas discharged from the combustion unit 36 is introduced to burn a combustible component included in the flue gas using a catalytic reaction; and a controller 15 for recovering, when the combustion unit 36 satisfies a condition that an anode off-gas is not ignited, a catalytic reaction by damaging a coat coating the combustion catalyst 28 and blocking the catalytic reaction, by causing steep change in temperature of the combustion catalyst 28 by a material pump 11a2 supplying a reforming material to the reforming unit 33 to burn the anode off-gas in the combustion catalyst 28.SELECTED DRAWING: Figure 1 |
