PROBLEM TO BE SOLVED: To prevent, in a fuel cell system comprising a combustion unit for combusting a combustible component supplied from a fuel cell, stop of combustion after ignition in the combustion unit.SOLUTION: A fuel cell system 100 includes: an oxygen ratio adjustment unit (controller 15) for making, in igniting a combustible component in a combustion unit 36, an oxygen ratio λ of a mixed gas led to the combustion unit 36 be an ignition correction oxygen ratio λ1 at which the mixed gas can be ignited and combusted; and an oxygen ratio change unit (controller 15) for changing, when combustion in the combustion unit 36 is stable, the oxygen ratio λ of a mixed gas led to the combustion unit 36 to a start normal oxygen ratio λ2-2. |
