PURPOSE: A fuel cell system is provided to stably control the load of a fuel cell by utilizing exhaust gas generated from a fuel electrode of a fuel battery as a heat source of a reforming reaction. CONSTITUTION: A fuel cell system(10) comprises a first mixing part(130) mixing fuel gas, a fuel cell stack(300) comprising a fuel electrode(320) and an air electrode(340), a reformer(310) reforming fuel gas to hydrogen by absorbing heat generated from the fuel electrode, a second mixing part(450) mixing exhaust gas discharged from the fuel electrode, and fuel gas supplied from the first mixing gas, and supplying the same to the reformer, and an exhaust gas heating part(430) heating the exhaust gas generated from the fuel electrode.
