PROBLEM TO BE SOLVED: To provide a fuel cell system in which a fuel gas is smoothly supplied to a fuel cell even in a low temperature environment.SOLUTION: A fuel cell system 1 comprises a fuel cell 2, a fuel supply passage 41 through which hydrogen is supplied to the fuel cell 2, a plurality of injectors 48 provided in parallel to the fuel supply passage 41, and a control unit 6 which controls opening and closing of the injectors 48 according to a requested amount of hydrogen to the fuel cell 2. When the temperature of the injectors 48 is not less than a prescribed temperature, the control unit 6 drives and controls one injector 48 in normal mode for supplying hydrogen to the fuel cell 2. When the temperature is less than the prescribed temperature, the control unit drives and controls all the injectors 48 in high use frequency mode for supplying hydrogen to the fuel cell 2.SELECTED DRAWING: Figure 2 【課題】低温環境下においても燃料電池へ燃料ガスが円滑に供給される燃料電池システムを提供する。【解決手段】燃料電池２と、燃料電池２へ水素が供給される燃料供給路４１と、燃料供給路４１に並列に設けられた複数のインジェクタ４８と、燃料電池２への水素の要求流量に応じてインジェクタ４８の開閉を制御する制御部６と、を有する燃料電池システム１であって、制御部６は、インジェクタ４８が所定温度以上の場合に、一つのインジェクタ４８を駆動して燃料電池２へ水素を供給させる通常モードでインジェクタ４８を制御し、インジェクタ４８が所定温度未満の場合に、全てのインジェクタ４８を駆動して燃料電池２へ水素を供給させる高使用頻度モードで制御する。【選択図】図２
