Beschreibung
Zusammenfassung:	A fuel cell system includes at least one fuel cell with an anode region and a cathode region, a burner for burning exhaust gases from the fuel cell and also additional fuel that may optionally be supplied, and a storage volume for intermediate storage of exhaust gases that flow away continuously or discontinuously via a valve from the anode region of the fuel cell, the storage volume being arranged between the anode region and the burner. The hot exhaust gases of the burner are expanded in an expansion device. A method of the operation of a fuel cell system involves controlling an additional valve after the storage volume.
