Abstract
A spring member is used in a fuel cell stack. The spring member includes a planar portion and a spring portion. The planar portion is joined to a separator in a state of surface contact with the separator. The spring portion extends from the planar portion and generates an elastic force for pressing the separator toward a power generation cell by receiving force in a stacking direction of a cell unit and undergoing bending deformation.
