Abstract: 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.

Abstract: The present invention presents a method for manufacturing a negative electrode of a solid oxide cell in a three-dimensional structure by using a pressurization process. In addition, the present invention proposes a structure in which the entire interface of a solid oxide cell is manufactured on the manufactured three-dimensional negative electrode substrate, through various deposition methods, in a three-dimensional structure so as to maximize a reaction area.

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.
