A cell including: a pair of interconnectors for electrically connecting unit cells; a membrane-electrode assembly disposed between the interconnectors; a pair of current collectors, each of which includes an abutting surface abutting against a corresponding one of the electrode layers and a first base material surface being in contact with a corresponding one of the interconnectors and electrically connecting the corresponding of the electrode layers and the corresponding one of the interconnectors; and elastic bodies biasing the abutting surface of at least one current collector toward a corresponding one of the electrode layers. The elastic bodies includes: a second base material surface being in contact with the first base material surface; and an elastic body protruding portion supporting the abutting surface and protruding from the second base material surface toward the corresponding one of the electrode layers to bias the abutting surface toward the corresponding one of the electrode layers.
