PROBLEM TO BE SOLVED: To provide a fuel battery device capable of suppressing carbon deposition while using vapor discharged from an anode of a fuel battery cell for vapor reforming in a reformer.SOLUTION: A fuel battery system comprises an anode off-gas passage 51 that allows an off-gas discharged from an anode AN of a fuel battery cell FC to flow and includes a circulation side passage 51B for guiding part of the off-gas to a reformer 25 and a combustion side passage 51C for guiding the remaining part of the off-gas to a combustor 55. When a flow rate of vapor flowing together with a fuel-gas in the circulation side passage 51B is low, a flow rate of air supplied to the reformer 25 is made to increase as compared with the case in which the flow rate of vapor is high.SELECTED DRAWING: Figure 1 |
