PROBLEM TO BE SOLVED: To provide a fuel cell system which reproduces a nitrogen adsorbent using energy effectively.SOLUTION: A fuel cell system 1 has: switching sections 31, 32, 33, 34 which at least switch between a first state in which air A1 from an air supply section 23 is supplied to a first suction section 15 and off-gas G4 from a fuel cell 11 is supplied to a second suction section 16 and a second state in which the air A1 from the air supply section 23 is supplied to the second suction section 16 and the off-gas G4 from the fuel cell 11 is supplied to the first suction section 15; and a control section 18 which controls a switching section so that the switching section can switch the state from the first state to the second state, or from the second state to the first state. |
