| description | To provide a butterfly valve which can effectively inhibit action of a valve body from being hindered by freezing at low temperature, and to provide a fuel cell system.SOLUTION: A fuel cell system 10 includes a butterfly valve 60 provided at a cathode system passage 46 connected to a fuel cell stack 12. The butterfly valve 60 has: a housing 72; a valve body 74; and a rotary shaft 76 for rotating the valve body 74. An axis of the rotary shaft 76 extends in a horizontal direction. A lower inner surface 92 of the housing 72 is formed with a projection part 94 which projects from the lower side to the upper side and is provided with a lower seat part 100 on which an outer peripheral edge of the valve body 74 is seated in a closed state of the valve body 74.SELECTED DRAWING: Figure 3
【課題】低温時に凍結によって弁体の動作が妨げられることを効果的に抑制することができるバタフライバルブ及び燃料電池システムを提供する。【解決手段】燃料電池システム１０は、燃料電池スタック１２に接続されたカソード系流路４６に設けられたバタフライバルブ６０を備える。バタフライバルブ６０は、ハウジング７２と、弁体７４と、弁体７４を回動させるための回動軸７６と、を有し、回動軸７６の軸線は、水平方向に延在し、ハウジング７２の下側内面９２には、下方から上方に向かって突出して弁体７４の閉状態で弁体７４の外周端が着座する下側シート部１００が設けられた突起部９４が形成されている。【選択図】図３ |
