Abstract
A fuel cell includes stacked power cells and an end cell. Each power cell includes a first plate and two first separators sandwiching the first plate. The end cell includes a second plate and two second separators sandwiching the second plate. Through holes formed in each plate and each separator form a power generating gas inlet passage extending in the power cells. The end cell has at least one of a “first structure,” in which a bottom wall of the through hole of the second plate or an upstream one of the second separators is downwardly recessed compared to corresponding portions of the power cells, and a “second structure,” in which a bottom wall of the through hole of the second plate or a downstream one of the second separators upwardly projects compared to corresponding portions of the power cells.
