<P>PROBLEM TO BE SOLVED: To appropriately control a wetting condition of a fuel electrode by appropriately controlling an amount of water contained in fuel gas supplied to a fuel cell, and to uniformize an amount of the fuel gas supplied to each of unit cells. <P>SOLUTION: The fuel cell system A includes a fuel cell stack 10 having the fuel cell to which an oxidant gas and the fuel gas are supplied so as to generate electric power by electrochemical reaction of the oxidant gas and the fuel gas, a fuel tank for supplying the fuel gas to the fuel cell, an ejector 30 provided on fuel supply piping 21 connecting the fuel cell and the fuel tank, and fuel circulation piping 31 for circulating anode off-gas delivered from the fuel cell to the ejector 30. In the ejector 30, the anode off-gas is mixed with the fuel gas supplied from the fuel tank, and the mixture is supplied to the fuel cell, and a catch tank 20 is provided on the fuel supply piping 21 between the ejector 30 and the fuel cell stack 10. <P>COPYRIGHT: (C)2011,JPO&INPIT |
