Abstract
On an anode side separator, an adhesive is applied linearly along the upper and lower edges of the four edges thereof, around a receiving part and around a through-hole and so on. On a cathode side separator, the adhesive is applied at the same locations as on the anode side separator. The adhesive functions as support members for supporting the fastening load on the edges of the separators.

1-7. (canceled)
A fuel cell including a stack of unit cells each including an electrolyte membrane, a pair of electrodes disposed on both sides of the electrolyte membrane, and a pair of separators disposed outside the paired electrodes and in which a fastening load is applied in a stacking direction to maintain a stacked state of the stack, comprising:
- through-holes formed through outer peripheral portions of the separators that allow at least a reactant gas or a fluid to flow through the separators;
- receiving parts formed on the separators into which the electrolyte membrane and the pair of electrodes are fitted;
- and
- seal members formed around the through-holes and around the receiving parts;
- wherein
- additional support members are disposed between the pairs of separators for supporting the fastening load in areas with no through-holes for at least the reactant gas or the fluid on the outer peripheral portions of the separators.
