The invention relates to a solid oxide fuel cell system, wherein planar fuel cells are arranged in stacked form and in this respect an integrated post-combustion of non-oxidized components, or of not fully oxidized components, in the exhaust gas can take place. The fuel cells of a system in accordance with the invention have a cathode-electrolyte-anode unit. A bipolar plate is arranged between two respective fuel cells and channels for the supply and removal of a fuel gas to anodes and of an oxidizing agent to cathodes are present. The exhaust gases at the anode side or at the cathode side are introduced via internal additional channels or directly into an afterburner in which a catalytic post-oxidizing of the exhaust gas mixture formed with the exhaust gas at the anode side and at the cathode side takes place. In this respect, a catalytic afterburner is associated with every single fuel cell or with a group formed of a plurality of fuel cells and the afterburners are arranged so that exhaust gas discharged from a fuel cell at the anode side or at the cathode side can enter directly into an afterburner.
