PURPOSE:To enhance energy efficiency of fuel, by setting a high temperature fuel cell in the half way of a connecting duct between gas turbines, in case of the gas turbine which obtains energy by successively feeding high pressure combustion gas to the plural gas turbines. CONSTITUTION:Combustion of air, compressed by a compressor 4 and preheated by a regenerator heat exchanger 5, and hydrogen gas, supplied from a fuel gas supply line 7, is performed in a combustor 6, in this way, the first gas turbine 1 is driven by the generated high pressure combustion gas. And a high temperature fuel cell 11, in which the combustion gas finishing work is fed by a connecting duct 10 causing oxygen in the combustion gas to react with the hydrogen gas from the fuel supply line 7 under existence of an electrolyte, emits thermal energy and electricity. Next, high temperature combustion gas, generated in said cell 11, is fed to the second gas turbine 2 performing work, thus a generator 3 is driven by the both gas turbines 1, 2. |
