<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of readily controlling such that the problem of a membrane hole opening, or the like, do not arise in an electrochemical type hydrogen pump, and moreover, that the hydrogen amount exhausted out of system together with impurities becomes sufficiently small. <P>SOLUTION: In the fuel cell system, in a rear stage of a first electrochemical type hydrogen pump 24, there is arranged a second electrochemical type hydrogen pump 25, having a construction/structure in which time required for diffusing hydrogen up to a portion near an anode exhaust gas exit port of its anode side passage is shorter than the first electrochemical type hydrogen pump 24. <P>COPYRIGHT: (C)2011,JPO&INPIT |
