<P>PROBLEM TO BE SOLVED: To provide an exhaust gas treatment device of a fuel cell capable of sufficiently bringing out ability of a dilution unit. <P>SOLUTION: This exhaust gas treatment device 25 of a fuel cell is provided with: a discharged fuel dilution unit 6 having an accumulation chamber 6A for accumulating hydrogen gas purged from a fuel cell stack; and an exhaust pipe 14 for passing a cathode offgas. The discharged fuel dilution unit 6 is equipped with: a hydrogen suction port 62b for sucking the hydrogen gas in the accumulation chamber 6A into the exhaust pipe 14; and an air supply port 62a for supplying the cathode offgas in the exhaust pipe 14 into the accumulation chamber 6A. A straightening means 63 for straightening the hydrogen gas to guide it to the hydrogen suction port 62b and for restraining diffusion of the cathode offgas supplied into the accumulation chamber 6A from the air supply port 62a is formed in the accumulation chamber 6A. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
