Abstract: When terminating power generation by a fuel cell 3 in a fuel cell system 1, an amount of a raw fuel material introduced to a reforming catalyst 2a of a reformer 2 is reduced. Here, before the temperature of the reforming catalyst 2a is lowered to the un-reformed gas generation temperature, an amount of water supplied to the reforming catalyst 2a is controlled to increase the temperature of the reforming catalyst 2a. Thus, upon termination of power generation in the fuel cell 3, no un-reformed gas is generated and the reformed gas is supplied to the fuel cell 3.

Abstract: In fuel cell system 1, at the stop of power generation in fuel cell 3, the amount of a source fuel introduced to a reforming catalyst 2a of a reformer 2 is reduced, but at this time, before the temperature of the reforming catalyst 2a falls to an unreformed gas generation temperature, air is introduced to the reforming catalyst 2a to raise the temperature of the reforming catalyst 2a. At this time, before the temperature of the reforming catalyst 2a falls to an unreformed gas generation temperature, at least one of heating the reforming catalyst 2a and introducing air into the reforming catalyst 2a is performed. This raises the temperature of the reforming catalyst 2a and therefore, the generation of the unreformed gas is prevented and the reformed gas is supplied to the fuel cell 3, at the stop of power generation in the fuel cell 3.
