Abstract
A cell structure for a fuel cell stack that is formed by stacking unit cells C each including a membrane electrode assemblyand a pair of separatorsholding the membrane electrode assemblytherebetween. The membrane electrode assemblyincludes a framein the periphery having such a size as to extend outward over the edges of the separators. Communication holesin communication with the front and back sides are formed in the framein an area from a sealing partbetween framesadjacent in the cell stacking direction to a sealing partsbetween the membrane electrode assemblyand the separators. The air in a space Q formed between the inner and outer sealing partsis allowed to be released to the outside through the communication holes, and a breakage of the adhesive of the sealing partsis thereby prevented.
