To provide a fuel cell system that includes a plurality of sets of fuel cell stacks and air supply means, and power storage means for supplying power to the air supply means, and in which the power storage means supplies electric power to the plurality of air supply means, and that can reduce the power consumption peak of the air supply means, and a control method during start-up of the fuel cell system.SOLUTION: A fuel cell system 300 drives either one of first air supply means 102a and second air supply means 102b when a first fuel cell set 109a and a second fuel cell set 109b are activated, and then drives the air supply means on one side such that the power peak of the air supply means on one side is positioned after an output voltage of the fuel cell stack on the other side reaches a first output value.SELECTED DRAWING: Figure 3 【課題】燃料電池スタック及び空気供給手段のセットと、空気供給手段に電力を供給するための蓄電手段と、を含み、燃料電池スタック及び空気供給手段のセットが複数であり、蓄電手段が複数の空気供給手段に電力を供給する燃料電池システムにおいて、空気供給手段の消費電力ピークを低減できる、燃料電池システム及び燃料電池システムの起動時における制御方法を提供する。【解決手段】第一の燃料電池セット１０９ａ及び第二の燃料電池セット１０９ｂの起動時に、第一の空気供給手段１０２ａ及び第二の空気供給手段１０２ｂのいずれか一方を駆動後、一方の側の燃料電池スタックの出力電圧が第一の出力値に達して以降に、他方の側の空気供給手段の電力ピークが位置するように他方の側の空気供給手段を駆動する、燃料電池システム３００。【選択図】図３
