Abstract
A passage bead seal of a fuel cell joint separator includes a straight portion and curved portions. An oxygen-containing gas bridge section connecting the inside and the outside of a portion surrounded by a passage bead seal includes inner tunnels and outer tunnels coupled to an inner side wall and an outer side wall of a straight portion, and protruding in a separator thickness direction. The tunnel height is determined to be smaller than the bead seal height by not less than a predetermined value in a manner that a line pressure applied by a compression load to a front end surface of the straight portion becomes the same as a line pressure applied by the compression load to a front end surface of the curved portion.
