A review of current performance of rare earth metal-doped barium zirconate perovskite: The promising electrode and electrolyte material for the protonic ceramic fuel cells
Rare-earth metal doped barium zirconate (RE+-BaZrO3) materials are ionic and electronic conductors currently showing double functions in the protonic ceramic fuel cells (PCFCs). Specifically, RE+-BaZrO3 are relevant as electrode and electrolyte for PCFCs. They have appreciable electron-ionic conductivity (e−/H+/O2−) at moderate temperature (≥500 °C) making them a better choice when compared to other perovskites. However, in these materials (RE+-BaZrO3), challenges such as weak proton uptake and insufficient catalytic sites still exist and need to be addressed. From physic-chemical perspectives, improvement can be made possible through deeper understanding of proton uptake mechanism and catalytic sites resulting from structure engineering. Based on that, this review focuses on importance of synthesis application for tuning the structural properties of RE+-BaZrO3 materials, and hence enhances their current performances. The current advances made through material modification are discussed too. The main emphasis and discussions are on RE+-BaZrO3 material design as electrode and electrolyte for PCFCs. The reaction mechanisms associated with the material proton uptakes are explicitly discussed. Putting all relevant analytical results into consideration, the primary approaches to improve the performance of the electrode and electrolyte-based on RE+-BaZrO3 materials are indicated.
期刊介绍:
Progress in Solid State Chemistry offers critical reviews and specialized articles written by leading experts in the field, providing a comprehensive view of solid-state chemistry. It addresses the challenge of dispersed literature by offering up-to-date assessments of research progress and recent developments. Emphasis is placed on the relationship between physical properties and structural chemistry, particularly imperfections like vacancies and dislocations. The reviews published in Progress in Solid State Chemistry emphasize critical evaluation of the field, along with indications of current problems and future directions. Papers are not intended to be bibliographic in nature but rather to inform a broad range of readers in an inherently multidisciplinary field by providing expert treatises oriented both towards specialists in different areas of the solid state and towards nonspecialists. The authorship is international, and the subject matter will be of interest to chemists, materials scientists, physicists, metallurgists, crystallographers, ceramists, and engineers interested in the solid state.
