Abstract
In a fuel cell stack, a plurality of projections are provided on a surface of a first end plate opposite to a cell stack body. The projections have support surfaces oriented in a stacking direction. The plurality of projections are overlapped with, or adjacent to the flow field seal as viewed in the stacking direction, and the support surfaces of the plurality of projections are positioned on a single plane surface perpendicular to the stacking direction.
