ABSTRACT:
There is disclosed a fuel cell system according to the invention comprising; a material gas feeder (1); a reformer (3); a fuel cell (4); a combustor (5); communication passages (6A-6E); and a controller (20),wherein during a shutdown period of the fuel cell (4), the controller (20) determines whether the fuel cell system is in a normal condition where a shutdown operation of the fuel cell (4) is performed; and wherein if the controller (20) determines that the fuel cell system is not in the normal condition, the controller (20) controls the material gas feeder (1) to execute a material gas feed process before a next ignition of the combustor (5), the material gas feed process being performed such that the material gas is supplied to a hydrogen-containing gas flow path constituted by the reformer (3) and the communication passages (6A-6E) located between the reformer (3) and the combustor (5).
