Abstract
A fuel cell stack has a plurality of laminated cell units, with each of the cell units including a membrane electrode assembly sandwiched between two separators, and cooling fluid passage channels are formed between each adjacent cell units for flowing cooling fluid. Displacement absorbing members have a plurality of displacement absorbing projections that absorb displacement along a laminated direction of the cell unit and are provided in the cooling fluid passage channels. The displacement absorbing projections of the displacement absorbing members are disposed so as to cancel out any bending moments generated on the cell unit.
