Abstract

A fuel cell seal structure includes stacked fuel cells and an electrolyte membrane or a film supported between the neighboring metal separators. Each of the stacked fuel cells includes neighboring metal separators each including a plate portion having a plate portion surface, a bead seal portion projecting from the plate portion surface and including a distal end having a distal end surface, an elastic body disposed on the distal end surface, and a stopper disposed on the plate portion surface and away from the elastic body. The neighboring metal separators are disposed such that elastic bodies are located opposed to each other in a stacking direction with the electrolyte membrane or the film supported in between the elastic bodies and face each other, and such that stoppers are located neighboring to each other in the stacking direction with the electrolyte membrane or the film supported in between the stoppers.
