PROBLEM TO BE SOLVED: To solve the problem due to temperature difference among various kinds of fuel gases.SOLUTION: In a power generation system 10, an exhaust fuel gas L3 discharged from an SOFC (solid oxide fuel cell) 13 is utilized as a fuel of a combustor of a gas turbine 11, and a part of a compressed air A2 compressed by a compressor 20 of the gas turbine 11 is utilized in driving the SOFC 13. The gas turbine 11 includes a first combustor 21A for burning a fuel gas L1 of a kind different from the exhaust fuel gas L3, a first turbine 22A driven by a combustion gas G1 supplied from the first combustor 21A, a second combustor 21B for burning the exhaust fuel gas L3, and a second turbine 22B shaft-connected with the first turbine 22A, and driven by a combustion gas G2 supplied from the second combustor 21B. |
