Beschreibung
Zusammenfassung:	A fuel cell system includes flow rate regulator (4A) for adjusting a flow rate of fuel gas on fuel gas circulation path (3A) for returning unused fuel gas exhausted from power generation output variable fuel cell stack (10A) to fuel gas supply path (2A) of power generation output variable fuel cell stack (10A). The fuel cell system includes ejectors (5B, 5C) at merging portions of respective fuel gas supply paths (2B, 2C) of power generation output constant fuel cell stack (11B, 11C) and respective fuel gas circulation paths (3B, 3C) for returning unused fuel gas exhausted from power generation output constant fuel cell stacks (11B, 11C) to fuel gas supply paths (2B, 2C) of power generation output constant fuel cell stacks (11B, 11C).
