SPRING MEMBER, FUEL CELL UNIT, AND FUEL CELL STACK

[PROBLEM] To provide a spring member, a fuel cell unit, and a fuel cell stack that can prevent a decrease in the power generation performance of a fuel cell caused by creep deformation of the spring member.[SOLUTION] A spring member 130 is used in a fuel cell stack 100 and comprises a planar portion...

Summary:[PROBLEM] To provide a spring member, a fuel cell unit, and a fuel cell stack that can prevent a decrease in the power generation performance of a fuel cell caused by creep deformation of the spring member.[SOLUTION] A spring member 130 is used in a fuel cell stack 100 and comprises a planar portion 131 that is joined to a separator in a state of surface contact with the separator 102, and a spring portion 132 that extends from the planar portion to generate an elastic force that presses the separator toward a power generation cell 101M by receiving force in a stacking direction Z of a cell unit and undergoing bending deformation.
