OPERATION METHOD FOR POWER GENERATION SYSTEM USING FUEL CELL

摘要

OPERATION METHOD FOR POWER GENERATION SYSTEM USING FUEL CELL Anode gas is fed to an anode chamber of a molten carbonate fuel cell and cathode gas is fed to a cathode chamber of the fuel cell. CO2 is separated from gases discharged from the cathode chamber of the fuel cell by a CO2 separator or by another fuel cell which serves as the CO2 separator. The separated CO2 is entirely or partially is introducted to the cathode chamber with gases discharged from the anode chamber such that a CO2 concentration in the cathode chamber is raised and the power generation is performed at a low CO2 utilization factor mode.
