A fuel cell includes a membrane electrode assembly and separators, an inner sealing member and an outer sealing member, a coolant channel, a base seal, an inner protrusion and an outer protrusion, and a middle protrusion. The membrane electrode assembly and the separators are stacked in a stacking direction. The inner sealing member and the outer sealing member are disposed between a first separator and a second separator. The base seal is disposed on at least one of separator surfaces between the second separator and a third separator. The inner protrusion and the outer protrusion are provided on the base seal so as to respectively overlap the inner sealing member and the outer sealing member when viewed in the stacking direction and so as to protrude between the second separator and the third separator in the stacking direction.
