A fuel cell stack includes a cell stack body including a plurality of stacked power generation cells together. A metal plate and an elastic seal member are overlapped with each other at a position facing a bead seal formed on an end metal separator. A support member includes a recess accommodating the metal plate. A gap is provided between an inner peripheral end of the metal plate and the recess, or between an outer peripheral end of the metal plate and the recess, for absorbing thermal expansion difference between the metal plate and the support member.
