PROBLEM TO BE SOLVED: To reduce an amount of water vapor to be added to a fuel gas.SOLUTION: A fuel cell hybrid power generation system 1 comprises: a first fuel cell 2 for generating an exhaust fuel gas by performing power generation using a first fuel gas; a moisture collection device 3 for generating a second fuel gas by removing moisture from the exhaust fuel gas; a second fuel cell 5 for performing power generation using the second fuel gas; and a control device 20 for controlling the moisture collection device 3 so that an amount of moisture removed from the exhaust fuel gas changes. The fuel cell hybrid power generation system 1 can adjust a S/C of the second fuel gas without adding water vapor to the second fuel gas, by adjusting the degree of removal of moisture from the exhaust fuel gas. Thereby, the fuel cell hybrid power generation system 1 can perform power generation at a low cost, by reducing an amount of water vapor added to the exhaust fuel gas. |
