| 摘要 |
The present invention relates to a heat recovery apparatus of a fuel cell system that supplies heat generated from various electric power generation elements including a fuel cell stack to hot water or to heating circulating water by effectively recovering the heat. A heat recovery apparatus of a fuel cell system includes: a first heat exchanger that recovers waste heat generated from a fuel cell stack; a second heat exchanger installed independently from the first heat exchanger, which recovers waste heat generated from a fuel treatment device or system pipes; and a heat storage tank supplying a heat exchange material to the first heat exchanger and the second heat exchanger and recovers the heat exchange material to supply waste heat included in the heat exchange material to the outside in accordance with an external heat demand. |
