Abstract
A power generation cell of a fuel cell stack includes a resin frame equipped MEA and a first metal separator and a second metal separator. In the power generation cell, the relationship of P>P>Pis satisfied, where Pindicates a first surface pressure applied from a first seal part and a second seal part to a resin frame member, Pindicates a second surface pressure applied from a first support part and a second support part to the overlap part, and Pindicates a third surface pressure applied from first flow field forming protrusions and second flow field forming protrusions to the power generation area.
