Abstract
To provide a solid oxide fuel cell system with which the durable lifespan of the reformer can be extended by suppressing temperature unevenness in the reformer. The present invention is a solid oxide fuel cell, including a fuel cell module, a reformer for producing hydrogen by POX, ATR, and SR steps; a fuel supply apparatus, a reform air supply apparatus, a water supply apparatus, a generating air supply apparatus, and a control device which, as the temperature inside the fuel cell module rises, executes in sequence POX, ATR and SR steps at predetermined respective temperature bands, and causes a rise in temperature at which electrical generation is possible; wherein the control device comprises a localized temperature rise suppression circuit which, by causing steam reforming to occur locally within the reformer in the POX step, suppresses localized temperature rises in the reformer.
