<P>PROBLEM TO BE SOLVED: To provide a fuel cell stack rapidly draining formed water from a power generating part by a simple and inexpensive configuration. <P>SOLUTION: In the fuel cell stack, a separator 3 is bonded with the generating part. First gas flow passages 4 and second gas flow passages 5 are formed on a surface (bonded with the power generating part) of the separator 3 to alternately extend in parallel. A reactive gas (a high humidity gas 6) of a relatively high humidity is supplied to the first gas flow passage 4 and a reactive gas (a low humidity gas) of a relatively low humidity is supplied to the second gas flow passage 5. <P>COPYRIGHT: (C)2009,JPO&INPIT |
