Abstract: Disclosed are a separator for fuel cells capable of minimizing the volume of a system and the use of sealants, and a stack for fuel cells, more particularly, a stack for solid oxide fuel cells, including the same. Specifically, by adding a metal sheet having a specific shape, position and size to the separator, the stress applied to the sealant can be uniformized, and thus the oxidizing agent and fuel can be separated and electrically isolated using only a piece of sealant. Therefore, the stack for fuel cells is characterized in that there is no variation in temperature, reactant concentration, power, or the like between respective unit cells, so delamination and microcracks do not occur, the volume is minimized, and the power density per unit volume is very high.

Abstract: Disclosed are a cathode for an all-solid-state battery including a cathode thin film for an all-solid-state battery or a cathode composite membrane for an all-solid-state battery, and an all-solid-state battery including the same. The cathode for an all-solid-state battery contains a grain that has a plane having a low surface energy and has a grain boundary arranged parallel to the electron movement direction, thus effectively lowering the interfacial resistance of the thin film while suppressing the dissolution and diffusion of the transition metal, thereby improving the cycle stability of the all-solid-state battery including the same.

Abstract: Provided is an interlayer for a thin electrolyte solid oxide cell, a thin electrolyte solid oxide cell including the same, and a method of forming the same. In various embodiments, functional elements (a fuel electrode, an electrolyte and a cathode) of the solid oxide cell are formed by means of a thin film process, and thus a nanostructure of the catalyst is not seriously lost due to agglomeration, different from a powder process. Thus, it is possible to accomplish catalyst activation according to a high specific surface area.
