摘要： Disclosed is a method for infiltrating a porous structure with a precursor solution by means of humidification. The infiltration method with a precursor solution using moisture control comprises the steps of: (S1) providing a substrate having porous structures deposited thereon; (S2) depositing, by electrospraying, a precursor solution on the substrate having porous structures deposited thereon; (S3) humidifying the porous structures having the precursor solution deposited thereon; and (S4) sintering the humidified porous structures.

摘要： Provided is a solid oxide cell including a fuel electrode layer, electrolyte layer and an air electrode layer, wherein a diffusion barrier layer is provided between the air electrode layer and the electrolyte layer, the diffusion barrier layer includes: a first diffusion barrier layer formed on the electrolyte layer and including a sintered ceria-based metal oxide containing no sintering aid; and a second diffusion barrier layer formed on the first diffusion barrier layer and including a sintered product of a ceria-based metal oxide mixed with a sintering aid, the first diffusion barrier layer includes a sintered product of nanopowder and macropowder of a ceria-based metal oxide, and the first diffusion barrier layer and the second diffusion barrier layer are sintered at the same time. The diffusion barrier layer is densified, shows high interfacial binding force and prevents formation of a secondary phase derived from chemical reaction with the electrolyte.

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： 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.
