PROBLEM TO BE SOLVED: To suppress deformation of a separator caused by power generation gas, while reducing and adjusting pressure loss in a cooling circulation path.SOLUTION: A fuel cell stack includes a plurality of fuel cells in which a pair of separators are disposed on both sides of a cell frame where a membrane electrode assembly is arranged, so as to section and form gas circulation paths for circulating two kinds of different power generation gas, respectively, more than one cell module M laminating these fuel cells each other, and a seal plate P1 interposed between these cell modules M, M and bonded. Separator displacement suppression means 50 for suppressing displacement of separators 25, 25 is interposed therebetween. |
