Abstract
There is realized a structure particularly suitable for inhibiting deformation of separators having a structure where the shapes of projections and recesses are inverted from each other on the front side and the back side of each separator as in a pressed metal separator. Between adjacent separators, there is formed either a power generation region where MEAs and frame members for holding at least a part of the MEAs are inserted or a refrigerant flow region where neither the MEAs nor the frame members are inserted. A deformation inhibiting region for inhibiting deformation of each separator is formed by a projection provided on the separator. Also, a projection for inhibiting the separator from deforming at the deformation inhibiting region or nearby is formed on each frame member. The projection is projected toward the back side of the deformation inhibiting region, where the deformation inhibiting region is a recess on the back side of the separator.
