Exhaust aftertreatment device with reformer and burner for a SOFC system

摘要

The present invention relates to an exhaust aftertreatment device (100a, 100b) for a fuel cell system (1000) comprising a fuel cell stack (200) having an anode portion (210) and a cathode portion (220) with a reformer (20) for supplying reformed anode supply gas to the anode portion (210), an exhaust gas burner (30) for burning fuel gas from the cathode portion (220), the exhaust gas burner (30) being annularly arranged around the reformer (20), and a fuel gas conduit portion (50) ) for supplying the cathode exhaust gas to the exhaust gas burner (30), the exhaust gas burner (30) having an exhaust gas burner oxidation catalyst (31) for heating fuel gas supplied from the cathode portion to the exhaust gas burner (30), and in the fuel gas passage portion (50 ) is arranged a heating means (40) for burning the fuel gas. Furthermore, the invention relates to a fuel cell system (1000) with the exhaust aftertreatment device (100a, 100b) according to the invention and to a motor vehicle with the fuel cell system (1000).
