PROBLEM TO BE SOLVED: To provide a fuel cell system capable of accelerating a rise of temperature of a compressor.SOLUTION: A fuel cell system (100) comprises: pressure control valves (34, 36) provided on a supply passage (30a) or a discharge passage (30b); and a bypass valve (35) provided on a bypass flow passage (30c) connected from the supply passage (30a) to the discharge passage (30b) without passing through a fuel cell (10). When activating the fuel cell system (100) under a low temperature environment having temperatures lower than those under a normal temperature environment, the pressure control valves (34, 36) adjust opening of the pressure control valves (34, 36) to raise pressure in the supply passage (30a) on the side from the fuel cell (10) to the compressor (32). At this time, the bypass valve (35) opens so that opening of the bypass valve (35) is higher than that of the bypass valve (35) at the time of activating the fuel cell system (100) under the normal temperature environment.SELECTED DRAWING: Figure 2 【課題】コンプレッサの昇温の迅速化を図ることができる燃料電池システムの提供。【解決手段】供給路（３０ａ）、又は排出路（３０ｂ）に設けられた圧力制御弁（３４、３６）と、燃料電池（１０）を経ることなく供給路（３０ａ）から排出路（３０ｂ）へ接続されるバイパス流路（３０ｃ）に、設けられたバイパス弁（３５）とを備える燃料電池システム（１００）である。常温環境下よりも温度が低い低温環境下において燃料電池システム（１００）を起動したとき、圧力制御弁（３４、３６）は、圧力制御弁（３４、３６）の開度を調整することによって、供給路（３０ａ）における燃料電池（１０）からコンプレッサ（３２）側までの圧力を上昇させる。バイパス弁（３５）はバイパス弁（３５）の開度が常温環境下において燃料電池システム（１００）を起動したときのバイパス弁（３５）の開度と比較して高くなるように開く。【選択図】図２
