| Abstract Scope |
Protonic ceramic electrochemical cells (PCECs) are promising devices for clean energy conversion, enabling efficient hydrogen production and power generation at intermediate temperatures. Practical deployment requires understanding how cell design and manufacturing decisions shape microstructure and electrochemical behavior. This talk presents work linking support-structure modifications to sintering, microstructural evolution, and cell performance. Through systematic variation of support parameters, we show how fabrication choices govern densification, interlayer compatibility, and microstructural features that control transport and reaction processes. These outcomes are connected to electrochemical performance under both fuel cell and electrolysis operation, revealing consistent relationships between how a cell is built and how it performs. Overall, this work establishes processing-microstructure-performance relationships to guide future design and manufacturing strategies. By identifying structural and fabrication factors that strongly affect cell quality and efficiency, the study provides a practical framework for developing high-performance PCECs and related solid oxide electrochemical systems. |
