To extend a usage period of a chemical filter while preventing an increase in the size and cost of the chemical filter.SOLUTION: A fuel cell system equipped with a fuel cell that generates electricity based on fuel gas and air includes a chemical filter that can remove an impurity in the air by chemical reaction, an air flow path that has a chemical filter flow path provided with the chemical filter and a bypass flow path bypassing the chemical filter and through which air is directed to the fuel cell through either the chemical filter flow path or the bypass flow path, a blower provided in the air flow path to supply air to the fuel cell by driving, and a switching valve that is provided in the air flow path and switches a flow path through which air toward the fuel cell passes to either the chemical filter flow path or the bypass flow path.SELECTED DRAWING: Figure 2 【課題】化学フィルタのサイズの大型化やコスト増を防止しつつ、化学フィルタの使用期間の長期化を図る。【解決手段】燃料ガスと空気とに基づいて発電する燃料電池を備える燃料電池システムは、空気中の不純物を化学反応によって除去可能な化学フィルタと、前記化学フィルタが設けられた化学フィルタ流路と、前記化学フィルタを迂回するバイパス流路とを有し、前記化学フィルタ流路および前記バイパス流路のいずれかを通って前記燃料電池に空気が向かう空気流路と、前記空気流路に設けられ、駆動することで前記燃料電池に空気を供給するブロワと、前記空気流路に設けられ、前記燃料電池に向かう空気が通る流路を前記化学フィルタ流路および前記バイパス流路のいずれかに切り替える切替弁と、を備えるものである。【選択図】図２
