A fuel cell stack includes cell modules (M) and a seal plate (P1). Each cell module (M) is formed by stacking fuel cells (20) each including a membrane electrode assembly (33) having an insulating member at its outer periphery portion and paired separators (40 and 41) sandwiching the membrane electrode assembly (33), and by attaching the insulating members of adjacent ones of the fuel cells (20) together. The seal plate (P1) is interposed between the stacked cell modules (M). The seal plate (P1) includes: manifold holes (M1, M3, M4, and M6) from which two kinds of power-generation gases flow in and out on each fuel cell separately; and a first seal member (51 to 54) provided along a peripheral portion of each of the manifold holes (M1, M3, M4, and M6) to seal a corresponding one of the power-generation gases flowing through the manifold hole (M1, M3, M4, or M6). |
