Festoxid-Brennstoffzellen-System

WO 2011015261 A1 UPAB: 20110223 NOVELTY - Solid oxide fuel cell system comprises planar fuel cells forming a stack comprising a cathode-electrolyte-anode unit, and a bipolar plate (5) that is arranged between two respective fuel cells and channels are present for the supply and removal of a fuel gas to anodes (2) and of an oxidizing agent to cathodes (1), where exhaust gas at the anode side or cathode side can be supplied 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. DETAILED DESCRIPTION - Solid oxide fuel cell system comprises planar fuel cells forming a stack comprising a cathode-electrolyte-anode unit, a bipolar plate (5) that is arranged between two respective fuel cells and channels are present for the supply and removal of a fuel gas to anodes (2) and of an oxidizing agent to cathodes (1), where exhaust gas at the anode side or cathode side can be supplied 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, where a catalytic afterburner (9) is associated with every single fuel cell or with a group formed from fuel cells; and in that the afterburners are arranged so that exhaust gas discharged from a fuel cell at the anode side or at the cathode side enters directly into an afterburner. USE - The solid oxide fuel cell system is useful for industrial applications. ADVANTAGE - The invention provides solid electrolyte fuel cell system which can be manufactured in an inexpensive and flexible manner
