PROBLEM TO BE SOLVED: To provide a fuel cell system capable of delivering hot water to a desired position with a simple configuration while giving priority to hot water production using waste heat of a fuel cell.SOLUTION: Storage water in a hot water tank 2 is heated by a heating device 6. A circulation passage 3 comprises a hot water takeout unit 8 which can take out hot water to a use point, and circulates hot water by a circulation pump 7 between itself and the hot water tank 2. A water supply tank 4 is installed at a higher place than the hot water tank 2. A hot water storage tank 5 is installed at a higher place than the hot water tank 2 and at a lower place than the water supply tank 4. The hot water storage tank 5 is connected to the water supply tank 4 via a water supply passage 21 and also connected to the hot water tank 2 via a hot water passage 22. Storage water is heated using waste heat of a fuel cell 10. Water is supplied from the water supply tank 4 to the hot water storage tank 5 and from the hot water storage tank 5 to the hot water tank 2 respectively using a water head pressure difference.SELECTED DRAWING: Figure 1 【課題】燃料電池の廃熱を用いた温水製造を優先しつつ、簡易な構成で所望箇所へ出湯可能な燃料電池システムを提供する。【解決手段】温水タンク２内の貯留水は、加温装置６により加温される。循環路３は、ユースポイントに向けて温水を取り出し可能な温水取出部８を有し、循環ポンプ７により温水タンク２との間で温水を循環させる。給水タンク４は、温水タンク２より高所に設置される。貯湯タンク５は、温水タンク２より高所であるが給水タンク４より低所に設置され、給水タンク４と給水路２１を介して接続される一方、温水タンク２と温水路２２を介して接続され、燃料電池１０の廃熱を用いて貯留水が加温される。給水タンク４から貯湯タンク５への給水と、貯湯タンク５から温水タンク２への給水とは、それぞれ水頭圧差を利用してなされる。【選択図】図１
