To provide a fuel cell cogeneration system which prevents the lack of hot water and improves the energy saving performance of the system by controlling the comfort of a demand for hot water supply firstly and by allowing for a demand for electric power secondly.
The fuel cell cogeneration system comprises an electric power load detection means 5; a thermal load detection means 19; an electric power load prediction means 21 and a hot water consumption prediction means 20 which predict the electric power and hot water consumption; and a control means which stops the operation of a fuel cell 1 by referencing to the predicted electric power load and the hot water consumption, and controls a response to a thermal load with the highest priority when making a determination that the predicted hot water consumption is more than the storage amount of the hot water obtained from the fuel cell by waste heat recovery. Therefore, this makes the operation rate of the fuel cell large (power generation capability large) in a condition like winter when a load of the hot water supply is maximum, makes the system operate to prevent the lack of the hot water, and allows people to use the hot water supply comfortably.
