Summary:PROBLEM TO BE SOLVED: To provide a fuel cell system equipped with a humidification device capable of efficiently humidifying a reaction gas supplied to a fuel cell. SOLUTION: This fuel cell system 100 is provided with: a fuel cell stack 60 generating power by being supplied with the reaction gas; a reaction gas supply means supplying the reaction gas to the fuel cell; and the humidification device 1A having a hollow fiber membrane 42 having moisture permeability, and executing moisture exchange, through the hollow fiber membrane 42, between the reaction gas supplied to the fuel cell stack 60 and off-gas exhausted from the fuel cell stack 60 to humidify the reaction gas. The fuel cell system is structured to increase the flow velocity of the off-gas in the humidification device 1A. COPYRIGHT: (C)2008,JPO&INPIT
