<P>PROBLEM TO BE SOLVED: To provide a fuel cell capable of well improving water drainage, surely supplying reaction gas, and securing a desired power generation performance. <P>SOLUTION: The unit cell 12 comprises a first and a second separators 16, 18 interposing an electrolyte membrane and electrode assembly 14. An oxidant gas passage 32 which communicates an oxidant gas entrance communicating hole 20a and an oxidant gas exit communicating hole 20b is formed at the first separator 16, and this oxidant gas passage 32 is split into an entrance side main passage groove 34 and an exit side main passage groove 36 respectively through a projected part 38. The entrance side main passage groove 34 and the exit side main passage groove 36 are communicated through a plurality of auxiliary passage grooves 42 formed at the projected part 38. <P>COPYRIGHT: (C)2007,JPO&INPIT |
