Tailoring an Interface Microstructure for High-Performance Reversible Protonic Ceramic Electrochemical Cells via Soft Lithography

“…Especially, because the majority of electrochemical reactions of SOFCs preferentially take place near the electrolyte/electrode interfaces despite the use of MIECs, the application of a micropatterned interface can also be one of the direct strategies to improve the performance of PCECs by increasing the effective reaction area along with the micropatterned interface. − Despite the significant potential of the micropatterned interface, it is extremely challenging to achieve it in multilayered ceramic cells through conventional micropatterning methods such as selective etching and micromachining. Because all components in ceramic cells are too fragile to be mechanically machined and too vulnerable to be chemically etched, the material integrity of the treated ceramic surface can be severely damaged after typical patterning processes, − deteriorating the mechanical stability of ceramic cells. These unfavorable material properties of ceramic components indicate a great need for a new micropatterning technology designed specially for ceramic cells.…”

“…In addition, the mechanical strength of ceramic oxide components could also be compromised due to the inherent fragility induced. 272,273 And the integrity of the treated interface could be severely damaged, and further investigation of the mechanical behavior and electrochemical performance stability over the long-term process is required. 272,273…”
