<P>PROBLEM TO BE SOLVED: To provide a hydrogen dilution device of a fuel cell which can dilute hydrogen to sufficiently low density and has no risk of a penetrated hole to be blocked up. <P>SOLUTION: The hydrogen dilution device 21 of a fuel cell includes a staying chamber 2 in which an anode offgas is stayed, an anode introduction passage 6 for introducing the anode offgas into the staying chamber 2, a cathode introduction passage for introducing a cathode offgas into the staying chamber 2, and an offgas exhausting passage 29 for exhausting the anode offgas and the cathode offgas. One open mouth end 30 of the offgas exhausting passage 29 is inserted into an open mouth end 28 of the cathode introduction passage 27 so that a gap is formed. <P>COPYRIGHT: (C)2009,JPO&INPIT |
