Abstract
There has been a problem that the cell units cannot bear the load exerted on the units while being stacked since a fuel cell stack including a refrigerant channel formed between cell units each having an even number of electrolyte/electrode structures (MEA) and metal separators which are alternated does not have any structure supporting the separators forming the refrigerant channel in a stacking direction. In order to solve the above problem, in each of a first power generating unit and a second power generating unit, projections formed at the buffer portions of the separators are disposed in the same positions in the stacking direction with the MEA interposed therebetween. Since between the first and second power generating units, the projections of the buffer portions are staggered, the projections of the first and second power generating units are thereby disposed in the same positions in the stacking direction.
