EXHAUST-GAS AFTERTREATMENT DEVICE WITH REFORMER AND BURNER FOR AN SOFC SYSTEM

摘要

The present invention relates to an exhaust-gas aftertreatment device (100a; 100b) for a fuel cell system (1000) which has a fuel cell stack (200) with an anode section (210) and a cathode section (220), with a reformer (20) for feeding reformed anode feed gas to the anode section (210), an exhaust-gas burner (30) for the combustion of combustion gas from the cathode section (220), wherein the exhaust-gas burner (30) is arranged in ring-shaped fashion around the reformer (20), and a combustion gas line section (50) for feeding the cathode exhaust gas to the exhaust-gas burner (30), wherein the exhaust-gas burner (30) has an exhaust-gas burner oxidation catalyst (31) for heating combustion gas which is conducted from the cathode section to the exhaust-gas burner (30), and a heating means (40) for the combustion of the combustion gas is arranged in the combustion gas line section (50). The invention also relates to a fuel cell system (1000) with the exhaust-gas aftertreatment device (100a; 100b) according to the invention and to a motor vehicle with the fuel cell system (1000).
