  "textContent": "An object of the present invention is to provide a fuel cell power generation system that can attain a higher fuel utilization rate and can also attain higher power generation efficiency simultaneously. The fuel cell power generation system includes an oxide-ion-conducting first fuel cell that performs reformation of a fuel containing hydrocarbon and power generation and a proton-conducting second fuel cell that performs power generation by being supplied with hydrogen from the first fuel cell . The fuel utilization rate of the first fuel cell can be set to 30% or lower, for example, and the fuel utilization rate of the second fuel cell can be set to 70% or higher, for example. By adopting such a multi-stage configuration, it is possible to increase the power generation efficiency as a whole and to also attain a high fuel utilization rate simultaneously.",
