PROBLEM TO BE SOLVED: To secure a humidifying amount demanded in case discharge gas discharged from a fuel cell is used as humidifying gas to reaction gas supplied for the fuel cell. SOLUTION: A fuel cell system 10 is constituted with a fuel cell 11, an ejector 15, which mixes the discharge gas discharged from the fuel cell 11 and a fuel gas, and makes it re-circulate to the fuel cell 11, a humidifying part 18 which humidifies the fuel gas with the moisture contained in the discharge gas, a gas-liquid separation part 17 which recovers condensation water from the discharge gas which flows out from the humidifying part 18, a fuel gas flow-way branching part 20 which branches the flow way of the fuel gas by an upstream side of the ejector 15, an water absorbing ejector 16 which mixes the condensation water recovered collected by the gas-liquid separation part 17, with the other one of the branched fuel gas, and a fuel gas flow-way junction part 24 which mixes the fuel gas which flows out of water absorbing ejector 16 into the fuel gas which flows out of the humidifying part 18, and supplies it to the fuel cell 11. |
