<P>PROBLEM TO BE SOLVED: To provide a fuel battery separator which can control flooding in a passage groove due to condensed water and improve uniformity of contact resistance and control deterioration of output performance due to occurrence of a current density distribution in an MEA surface and control occurrence of a partial deterioration of the MEA, and provide a fuel battery cell provided with the separator. <P>SOLUTION: The fuel battery separator is provided with a passage which is formed by connecting passage grooves 23 made by a plurality of linear ribs 22 with a recess portion 24 in which a plurality of isolated projections 25 stand up from a bottom surface, and a height of the isolated projections 25 is higher than the linear ribs 22. The separator is one of a pair of separators pinching an MEA, and a gap in the projected part where the pair of the separators pinch the MEA is narrow. <P>COPYRIGHT: (C)2008,JPO&INPIT |
