Abstract: A method for preparing a sulfide-based solid electrolyte which is stable upon exposure to the air is provided. Specifically, a stabilization layer is formed on the surface of a sulfide-based solid electrolyte particle through treatment with a reactive gas.The sulfide-based solid electrolyte with superior air stability can be obtained because oxidation or reduction reactions with water, etc. in the air occur on the stabilization layer rather than on the sulfide-based solid electrolyte particle.

Abstract: Disclosed is a method of manufacturing a solid oxide fuel cell including a multi-layered electrolyte layer using a calendering process. The method for manufacturing a solid oxide fuel cell is a continuous process, thus providing high productivity and maximizing facility investment and processing costs. In addition, the solid oxide fuel cell manufactured by the method includes an anode that is free of interfacial defects and has a uniform packing structure, thereby advantageously greatly improving the production yield and power density. In addition, the solid oxide fuel cell has excellent interfacial bonding strength between respective layers included therein, and includes a multi-layered electrolyte layer in which the secondary phase at the interface is suppressed and which has increased density, thereby advantageously providing excellent output characteristics and long-term stability even at an intermediate operating temperature.

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: 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.
