FUEL CELL SYSTEM AND METHOD FOR CONTROLLING FUEL CELL SYSTEM

Japanese Patent JP2018006168

A

PROBLEM TO BE SOLVED: To provide a fuel cell system capable of further improving turbine efficiency, and a method for controlling the fuel cell system.SOLUTION: A fuel cell system comprises an operation state detecting unit which detects an operation state of a fuel cell, and an operation control device which controls a fuel supply device and an oxidant supply device by a signal from the operation state detecting unit. The fuel cell system further comprises a liquid water supply unit which supplies the liquid water discharged from a fuel cell to a combustor. The oxidant supply device comprises a compressor which supplies an oxidant to a cathode electrode of the fuel cell, a turbine which drives the compressor, and a combustor which generates a combustion gas which drives the turbine. The operation control device comprises a liquid water flow rate control unit which controls a combustor supply liquid water flow rate which is a flow rate of the liquid water supplied to the combustor on the basis of a liquid water flow rate control parameter containing any one of load of the fuel cell, target power of the compressor, target recovery power of the turbine, and a target inlet temperature of the turbine.SELECTED DRAWING: Figure 10
