Solid oxide electrolyte including thin film electrolyte layer of multiple repetitive structures, method for manufacturing the same, solid oxide fuel cell and solid oxide electrolysis cell comprising the same

摘要

The present invention relates to a solid oxide electrolyte including a thin film electrolyte layer having a multiple repeat structure capable of solving problems such as low reproducibility and durability of the thin film electrolyte, a manufacturing method thereof, a single cell including the same, a solid oxide fuel cell including the single cell, and The present invention relates to a solid oxide electrolytic cell including a single cell, wherein the multi-layered electrolyte layer has an advantage in that the stress of the adjacent electrolyte layers can be stably distributed due to a difference in thermal expansion coefficient at the interface adjacent to each other.
