PROBLEM TO BE SOLVED: To accelerate heating of a selective oxidation catalyst in warm-up of a CO remover for a fuel cell system. SOLUTION: A bypass 10 is provided to an air supply line 9 for supplying air 5 to a CO remover 3 and a heating part 10a of the bypass 10 is provided in a flue gas line 6b in a combustor 6. In warm-up time of the remover 3, an air switch valve 9a is turned so that the air 5 may be introduced into the bypass 10. Using a high temperature exhaust gas of the reformed gas burnt in a burner 6a of the combustors 6, the air 5 is preheated in the part 10a. The preheated air is supplied to the remover 3 so that the selective oxidation catalyst is heated. After completion of heating, the valve 9a is turned for ceasing air preheating. |
