Title:
FUEL CELL SYSTEM COMPRISING HEAT EXCHANGER USING COMBUSTION EXHAUST GAS
Document Type and Number:
WIPO Patent Application WO/2017/222267
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a solid oxide fuel cell system for increasing the operation efficiency of a burner by preheating a fuel or the air, supplied to the burner, by means of a high-temperature combustion exhaust gas discharged from the burner inside the fuel cell system. A fuel cell system comprising a heat exchanger using a combustion exhaust gas, for attaining the purpose, comprises: a hot box formed from a heat insulating material; a fuel cell stack disposed inside the hot box and comprising a cathode, electrolyte and an anode; a high-temperature heat exchanger which is disposed inside the hot box, receives a fuel gas, produces an anode gas comprising hydrogen, and supplies the anode gas to the anode in the fuel cell stack; a burner which is disposed inside the hot box, receives the fuel gas and the air, produces a high-temperature combustion exhaust gas, and supplies the combustion exhaust gas into the fuel cell system as a heat source; and a heat exchanger, for re-recovery, which is disposed inside the hot box, is provided on an air supply line, for the burner, supplying the air from the outside of the hot box to the burner, and preheats the air, supplied to the burner through the air supply line for the burner, by means of the high-temperature combustion exhaust gas.
