Abstract
A fuel cell stack 100 includes a fuel cell stack 10, and an end plate 30 placed at an end of the fuel cell stack 10. The end plate 30 includes a metallic plate-like body 32, and a resin layer 60 formed on a surface 32b of the plate-like body 32. The plate-like body 32 includes flow holes 39 for a reactant gas and a cooling medium, and a stripe-shaped protrusion 38 protruding from the surface 32b and which divides the surface 32b into an inner area containing the flow holes 39 and an outer area outside the inner area. The protrusion 38 includes a vertical portion 38a protruding from the surface 32b, and a jutted portion 38b jutted from a distal end of the vertical portion 38a toward the inner area. The resin layer 60 is formed in the inner area to cover a surface 38as of the vertical portion 38a facing the inner area as well as at least part of the jutted portion 38b.
