摘要： 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.

摘要： Provided is a method for manufacturing a sintered body for an electrolyte and an electrolyte for a fuel cell using the same. More particularly, the following disclosure relates to a method for preparing an electrolyte having a firm thin film layer by using a sintered body having controlled sintering characteristics, and application of the electrolyte to a solid oxide fuel cell. It is possible to control the sintering characteristics of a sintered body through a simple method, such as controlling the amounts of crude particles and nanoparticles. In addition, an electrode using the obtained sintered body having controlled sintering characteristics is effective for forming a firm thin film layer. Further, such an electrolyte having a firm thin film layer formed thereon inhibits combustion of fuel with oxygen when it is applied to a fuel cell, and thus shows significantly effective for improving the quality of a cell.

摘要： 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.

摘要： 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.
