PROBLEM TO BE SOLVED: To control hot water for bath for 24 hours by effectively using exhaust heat of a fuel cell. SOLUTION: This fuel cell power generation system is provided with a fuel cell 1, a heat exchanger 4, a bathtub 3, a circulation passage 33 and a heater 5, heats water flowing inside the circulation passage 33 through the heat exchanger 4 by the exhaust heat of the fuel cell 1 and adjusts the temperature of the water in the bathtub 3 by the heated water. A fuel cell control part 111 controls the operation of the fuel cell 1 so that the temperature of the water in the bathtub 3 is set at a predetermined value. A heater control part 112 operates the heater 5 so as to compensate the heat exchange by the exhaust heat and sets the temperature of the water in the bathtub 3 at the predetermined value. With this structure, the fuel cell system can maintain the water temperature in the bathtub 3 by using the exhaust heat. |
