<P>PROBLEM TO BE SOLVED: To enable to attain operation of fuel cell with an appropriate humidifying amount and downsizing of a humidifier by improving humidifying efficiency of air to be supplied to the fuel cell. <P>SOLUTION: The fuel cell system includes: a fuel cell 10 in which oxidant gas and fuel gas are supplied and which generates power by electro-chemical reaction of these oxidant gas and fuel gas; a humidifier 40 which transfers moisture contained in the oxidant gas discharged from the fuel cell 10 to the oxidant gas to be supplied to the fuel cell 10; a compressor 30 which compresses the oxidant gas humidified by the humidifier 40 and sends to the fuel cell 10; and a condensing means 60 which condenses power generation produced water discharged from the fuel cell 10 and stores it. The condensed water stored by the condensing means 60 is supplied to the spacing between the humidifier 40 and the compressor 30 at the upstream of the fuel cell 10. <P>COPYRIGHT: (C)2010,JPO&INPIT |
