Beschreibung
Zusammenfassung:	In a solid oxide fuel cell module ( 1 ) incorporating a burner ( 6 ) not only in an oxidizer side burner ( 5 ) of the module ( 1 ) but also in a fuel side, directly heating from both sides by a combustion gas, and starting for a short time, a combustion state of the fuel side burner is kept well, and a short-time start is securely achieved. A cooling piping ( 17 ) is provided in a burner main body ( 61 ) and a premixing chamber ( 62 ) of the fuel side burner ( 6 ), and is connected to a heat recovery system ( 16 ) so as to supply a cooling medium, thereby cooling the fuel side burner ( 6 ). Further, a heat held by the cooling medium is recovered by a heat exchanger ( 18 ) connected to an outlet side of the heat recovery system ( 16 ). A back fire (an abnormal combustion) of the burner is prevented, the module is uniformly heated, and a secure short-time start is achieved, by cooling the fuel side burner ( 6 ) so as to adjust temperature. Further, a combined efficiency of the module is improved by utilizing the recovered surplus heat.
