Abstract
To provide an electrochemical cell, an electrochemical cell device, a module, and a module storage device that can improve performance.SOLUTION: An electrochemical cell comprises a solid electrolyte layer, and a first electrode. The solid electrolyte layer includes first material having a rare earth element dissolved in a solid state and having ion conductivity. The first electrode includes a first rare earth element, and has a first surface in contact with the solid electrolyte layer and a second surface on the opposite side of the first surface. The first electrode has a larger content ratio of the first rare earth element on the first surface side than the second surface side.SELECTED DRAWING: Figure 3A
