Solid oxide fuel cell system

A solid oxide fuel cell system, comprising:

• a plurality of planar fuel cells form a stack, comprising a bipolar plate arranged between two respective fuel cells, the fuel cells respectively including a cathode-electrolyte-anode unit, wherein, the respective anodes and the cathodes are formed at two oppositely arranged sides of a solid electrolyte in an electrochemically active region of the fuel cell, and wherein openings formed in the solid electrolyte present channels for at least one of the supply and removal of at least one of a fuel gas to anodes, an oxidizing agent to cathodes, and an exhaust gas, wherein the exhaust gas at the anode side or cathode side is supplied via channels or directly into an afterburner configured to permit a catalytic post-oxidizing of an exhaust gas mixture formed with the exhaust gas at the anode side and at the cathode side, wherein webs provide an electrically conductive connection between the cathodes and bipolar plates, wherein a catalytic afterburner is associated with every single fuel cell or with a group formed from a plurality of fuel cells, and the afterburners are arranged such that exhaust gas discharged from a fuel cell at the anode side or at the cathode side enters directly into an afterburner.
