摘要： A fuel cell stack is assembled by alternately stacking a membrane electrode assembly (ME) (1) having a reaction surface (2A, 2B) and a separator (3A, 3B) having a reactive gas passage (9, 10) facing the reaction surface (2A, 2B). A supply manifold (6A, 6B) supplying reactive gas to the reactive gas passage (9, 10) passes through a first region on one side of the reaction surface (2A, 2B). A positioning hole (5A) is formed in the ME (1) and the separator (3A, 3B) in a second region situated on the opposite side of the reaction surface (2A, 2B). By fitting a through-pin (5B) in the positioning hole (5A), position offset of the reaction surface (2A, 2B) accompanying the stacking procedure is centered on a part with high reactive gas concentration, and deterioration due to the shortage of reactive gas in the offset reaction surface (2A, 2B) is prevented.
