Abstract:
1. A fuel cell employing power generation units that have an electrolyte membrane and electrodes respectively disposed to either side of the electrolyte membrane, the fuel cell comprising: a stack that includes a stacked plurality of the power generation units; a clamping member that clamps the stack in the stacking direction; and a shear elastic member interposed between the clamping member and an end face of the stack in the stacking direction, and configured to elastically deform in a shearing direction which lies orthogonal to the stacking direction, thereby causing the stack to displace in the shearing direction, wherein an amount of elastic deformation of the shear elastic member in the shearing direction is greater than an amount of elastic deformation of the stack in the shearing direction, one of a cushion member and a space is provided between a tension plate and an assembly of the stack and the shear elastic member, and the one of the cushion member and the space extends along an entire length of the stack and abuts the shear elastic member.
