A fuel cell includes a plurality of power generation cells (12) each having a first separator (14). The separator (14) has a fuel gas flow field (36). A fuel gas supply passage (32a) extends through one corner of the power generation cell (12) in the stacking direction, a fuel gas flowing through the fuel gas supply passage (32a) into a fuel gas flow field (36). An inlet buffer (38) is provided upstream of the fuel gas flow field (36). The fuel gas supply passage (32a) and the inlet buffer (38) are connected by a plurality of inlet connection grooves (64a). The inlet connection grooves (64a) are inclined from a direction perpendicular to a wall surface (66a) of the fuel gas supply passage (32a) toward the center of the fuel gas flow field (36). |
