PURPOSE:To increase temperature and pressure easily and quickly at starting of operation by installing a combustion chamber near a gas inlet of turbine, and forming passages for supplying a part of fuel and a part of exhaust gas from a cathode to the combustion chamber. CONSTITUTION:A combustion chamber is installed in a gas inlet of a gas turbine, and passages for supplying a part of fuel cell fuel and a part of exhaust gas from a cathode of fuel cell are formed. A fuel cell power generating plant is started in such a way that a part of fuel gas is introduced into a combustion chamber 29 of the inlet of a gas turbine 34 to operate the gas turbine, then a compressor 8 is drived by the gas turbine, and compressed air and fuel are supplied to a cathode 7 and an anode 6 respectively to increase pressure, then a part of fuel is supplied to a catalyst burner 18 and residual fuel is bypassed to supply to the combustion chamber to gradually increase temperature of a mixture gas for supplying to the cathode, and the temperature of fuel cell is increased. Thereby, installation cost, preliminary fuel, and starting loss can be decreased. |
