PROBLEM TO BE SOLVED: To provide an exhaust heat recovery system of a solid polymer type fuel cell which can decrease a tank capacity to store hot water and supply the hot water all the time. SOLUTION: The constitution of an exhaust heat recovery system collecting the waste-heat when a solid polymer type fuel cell 6 is used to generate power has the first hot water storage part 112A and the second hot water storage part 112B. At the first hot water storage part 112A, the waste-water is collected by the power generation of the day and the hot water is stored, and the temperature of the stored hot water is raised by the midnight power which uses commercial power supply, and hot water is supplied in the daytime of the next day. At the second hot water storage part 112B, when the hot water of the first hot water storage part 112A is supplied, the waste-heat by the power generation is recovered and the hot water is stored, and the midnight power using commercial power supply raises the temperature of the stored hot water, and the hot water is supplied in the daytime of the next day. |
