Zusammenfassung:	In order to protect the temperature of an exhaust stream in an exhaust line, even if the temperature of the exhaust stream discharged from a fuel cell exceeds a temperature during rated operation, a power generation system has: an SOFC; an exhaust air line or an exhaust fuel line, wherein the exhaust air line and exhaust fuel line carry exhaust air and exhaust fuel gas discharged from the SOFC, respectively; a temperature detector for detecting the temperature of the exhaust air or the exhaust fuel gas discharged from the SOFC or the temperature of the exhaust air line or the exhaust fuel line; an exhaust cooling device for cooling the exhaust air in the exhaust air line or the exhaust fuel gas in the exhaust fuel line; and a control device for activating the exhaust cooling device when the temperature detected by the temperature detector exceeds a predetermined temperature.
