<P>PROBLEM TO BE SOLVED: To provide an exhaust heat recovery system with excellent energy efficiency, capable of storing a heating medium at high temperature. <P>SOLUTION: The exhaust heat recovery system includes a heat storage tank TNK which can store heat by storing a heating medium, and recovers the exhaust heat of a fuel cell FC by causing the heating medium to communicate between a first heat exchange part 1 to which the exhaust heat from the fuel cell FC is supplied and the heat storage tank TNK. It includes a pre-heating means H which utilizes the heat contained in the heating medium after flowing out of the first heat exchange part 1 but before being stored in the heat storage tank TNK, to perform pre-heating treatment on the heating medium after being taken out of the heat storage tank TNK but before flowing into the first heat exchange part 1, and a control means C which controls a circulation mode of the heating medium and operation of the pre-heating means H. <P>COPYRIGHT: (C)2012,JPO&INPIT |
