In a fuel cell stack 10 in which a plurality of cell units A1 are laminated, the cell units including a membrane electrode assembly 30 sandwiched between two separators 40 and 41, and cooling fluid passage channels S3a and S3b are formed between each adjacent cell units A1 for flowing cooling fluid, displacement absorbing members Ca and Cb having a plurality of displacement absorbing projections 50 that absorb displacement along a laminated direction ± of the cell unit A1 are provided in the cooling fluid passage channels S3a and S3b, and the displacement absorbing projections 50 of the displacement absorbing members Ca and Cb are disposed so as to cancel out any bending moments generated on the cell unit A1. |
