POWER GENERATING SYSTEM, METHOD FOR OPERATING POWER GENERATING SYSTEM, AND CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To appropriately control an inner pressure of a fuel battery in a start-up or a shut-down.SOLUTION: In a start-up or a shut-down of a fuel battery module 2, an opening of a fuel flow control valve 401 controlling a flow rate of gas passing through a fuel pipe 310 for supplying fuel gas F1 to the fuel battery module 2 is controlled so that a difference between the pressure of discharge fuel gas F2 discharged from the fuel battery module 2 and the pressure of compressed-air O1 purified by an air compressor 4 driven by drive of a turbine 6 falls within a predetermined range.
