Abstract

The invention relates to an exhaust tract (100) for a fuel cell system (109), wherein the exhaust tract (100) comprises a main gas line (101) and an auxiliary gas line (103), wherein the main gas line (101) comprises a cathode air interface (105) for connecting to a cathode tract (107) of the fuel cell system (109) and a flushing interface (111) for connecting to a flushing line (113) of the fuel cell system (109), wherein the auxiliary gas line (103) is arranged behind the main gas line (101) in the flow direction of exhaust air flowing out of the cathode tract (107) into the main gas line (101), wherein the exhaust tract (100) comprises a number of secondary air openings (117) in a region behind the main gas line (101) in the flow direction for intaking secondary air by means of an exhaust flow flowing into the exhaust tract (100).
