UNIT CELL, AND ASSEMBLY COMPRISING UNIT CELL AND SPACER

摘要

[Problem] To provide a unit cell that can be reduced in size while suppressing electrical leakage caused by condensation, even when using a sealing member in which an end portion of a metal layer is exposed.[Solution] A unit cell 110 comprises a cell body 110H, an electrode tab 112 (an anode side electrode tab 112A and a cathode side electrode tab 112K), and a sealing member (a laminate film 113). The cell body includes a power-generating element and is formed into a flat shape. The anode side electrode tab and the cathode side electrode tab extend out from the cell body. A pair of the laminate films includes a sheet-shaped metal layer 113M, and a sheet-shaped insulating layer 113N that covers and insulates the metal layer from both sides, and sandwiches and seals the cell body. In the pair of laminate films 113 an exposed end portion 113e of a metal layer is spaced from a surface 113f of the insulating layer, while bending at least a portion of an outer edge 113d.
