Abstract
The fuel cell stack FS includes; a stacked plurality of single cells C each including a frameof a membrane electrode assemblyand a pair of separators; and a sealing memberdisposed between the plurality of single cells C. The pair of separatorsinclude respective supporting portionsthat are in contact with the frame, and the sealing memberis disposed on one supporting member. Further, the supporting portionsof the separatorshave different sizes so that an overlapped portion W is formed in which a base surfacewhere the supporting portionof one separatoris in contact with the frameis overlapped with a top surfacewhere the supporting portionof the other separatoris in contact with the framein the stacking direction. The overlapped portion W receives and transmits reaction force of the sealing memberbetween the single cells, which prevents narrowing of gas channels or decrease of the sealing surface pressure.
