<P>PROBLEM TO BE SOLVED: To improve recovery efficiency of moisture contained in offgas exhausted from a fuel cell, in a fuel cell system circulating anode offgas exhausted from the fuel cell back to the fuel cell. <P>SOLUTION: The fuel cell system is provided with a fuel cell 1 generating power by electrochemical reaction of hydrogen and oxidizing gas, an offgas circulating channel 32 guiding anode offgas exhausted from the fuel cell 1 at an anode side to the fuel cell, an offgas pump 3 fitted to the offgas circulation channel 32 for pressure-pumping the anode offgas of the offgas circulating channel to the fuel cell 1, a channel cooling means 20 cooling at least a part of the offgas circulation channel 32 with a heating medium, and a gas liquid separating means 4 for separating moisture contained in the anode offgas flowing in the offgas circulation channel cooled by the channel cooling means. <P>COPYRIGHT: (C)2008,JPO&INPIT |
