PROBLEM TO BE SOLVED: To provide a fuel cell power generation system enhancing the total cost efficiency by appropriating the production quantity (hot water storage volume) of hot water. SOLUTION: The hot water produced by waste heat from a fuel cell 11 is stored in a hot water storage tank 19 via a pipe 18 so as to be fed. When the fuel cell 11 is made to generate such power as causing waste heat capable of producing the hot water, a control device 17 controls the opening/closing of a valve 20 so as to feed the hot water to the hot water storage tank 19. A signal related to the hot water volume of the hot water storage tank 19 is constantly inputted from a hot water gage 22 provided in the hot water storage tank 19 into the control device 17. The control device 17 determines a target hot water storage volume of the hot water storage tank 19 based on the hot water consumption pattern grasped from the signal, and the feed volume of the hot water to the hot water storage tank 19 is controlled by controlling the action of the fuel cell 11 so that the hot water storage volume of the hot water storage tank 19 reaches the target hot storage volume. This constitution can suppress the excessive production of the hot water. |
