<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of suitably separating moisture in anode offgas without enlarging a gas-liquid separator. <P>SOLUTION: The fuel cell system 1 includes a fuel cell stack 20 generating power by supplying hydrogen to an anode and air to a cathode; fuel gas supply piping through which fuel gas supplying from a hydrogen tank 31 to the fuel cell stack 20 flows; fuel gas circulation piping through which anode offgas exhausted from the anode of the fuel cell stack 20 is returned to the fuel gas supply piping and hydrogen is circulated; a gas-liquid separator 34 arranged in the fuel gas circulation piping and separating moisture in the anode offgas; and a projecting part 11 projecting from the inner surface of the fuel gas circulation piping between the fuel cell stack 20 and the gas-liquid separator 34 toward the inside. <P>COPYRIGHT: (C)2009,JPO&INPIT |
