摘要： A supply path (22) of hydrogen gas in a fuel cell system (1) connects a plurality of fuel cell stacks (10A, 10B) in series with each other. The supply path (22) includes a downstream supply path (22B) configured to supply the fuel cell stack (10B) on a downstream side with exhaust gas of hydrogen gas supplied to the fuel cell stack (10A) on an upstream side, without circulating the exhaust gas to the fuel cell stack (10A) on the upstream side, and a circulating path (24B) configured to circulate exhaust gas from the fuel cell stack (10B) on the downstream side to the fuel cell stack (10B) on the downstream side.
