固体氧化物燃料电池的纳米结构阴极能够有效地提升电极的电化学性能以及电池的输出功率,具有良好的应用前景.本文主要介绍纳米结构阴极的长期稳定性以及电极稳定性的理论模型.纳米结构阴极具有良好的长期稳定性.由于尺寸效应,纳米结构能够抑制颗粒的高温生长,并且可以显著减小电解质和催化剂之间热膨胀不匹配带来的微观应力,使得两相之间保持良好的连接性.同时,纳米结构能够很好地抵抗热循环导致的颗粒间界面断裂行为,并在热循环中保持颗粒间的良好连接.La0.8Sr0.2MnO3-δ和La0.6Sr0.4Co0.2Fe0.8O3-δ等阴极材料在使用纳米结构技术后,阴极性能提升了2.3～78倍,并在超过1000 h的测试中保持稳定的功率输出.
