Protonic ceramic fuel cells and electrolysis cells represent low- and intermediate-temperature electrochemical devices, which allow chemical-to-electrical energy conversion with very high efficiency and low environmental impact. In order to ensure the long-term operability of these devices, as well as to provide for their up-scaling, a number of existing challenges associated with chemical and thermal incompatibilities pertaining to the functional materials remain to be overcome. This work presents a comprehensive overview of new electrode materials based on barium cerate/zirconate. The structural fragments of these materials are similar to those of the proton-conducting Ba(Ce,Zr)O3 electrolytes, which causes superior chemical compatibility between different functional materials. The primary emphasis of the research is on the functional properties of these materials such as chemical stability, thermal expansion behaviour and transport features. This in turn determines the electrochemical performance of the designed electrodes. In addition, the possibility of obtaining triple-conducting materials is discussed as means of designing electrodes with a high electrochemical active surface area required for the design of high-performance protonic ceramic fuel and electrolysis cells.

The bibliography includes 208 references.

用于质子陶瓷电化学电池的 Ba(Ce,Zr)O3 基电极:实现高度兼容的功能和三导电行为

质子陶瓷燃料电池和电解电池代表了低温和中温电化学装置,它们允许以非常高的效率和低环境影响进行化学到电能的转换。为了确保这些设备的长期可操作性,以及提供它们的规模化,与功能材料相关的化学和热不相容性相关的许多现有挑战仍有待克服。这项工作全面概述了基于铈酸钡/锆酸盐的新型电极材料。这些材料的结构片段类似于质子传导 Ba(Ce,Zr)O 3的结构片段电解质,这导致不同功能材料之间具有优异的化学相容性。该研究的主要重点是这些材料的功能特性,例如化学稳定性、热膨胀行为和传输特性。这反过来又决定了设计电极的电化学性能。此外,讨论了获得三导电材料的可能性,以作为设计高性能质子陶瓷燃料和电解电池所需的高电化学活性表面积的电极的方法。
