摘要

摘要以镧锶铁氧体为基础的透辉石类氧化物被认为是很有前途的电极材料，可用于各种类型的燃料电池，而通过用高电荷的铁活性阳离子部分取代铁来改性这些材料的策略已被证明是提高其化学稳定性的有效方法。在这项研究中，首次展示了基于 La0.5Sr0.5Fe1 - xNbxO3 - δ 的微管氧膜的渗透性研究结果。研究发现了氧化物大量扩散的活化能（20 ± 4 kJ/mol）。

Oxygen Transport in Microtubular Membranes La0.5Sr0.5Fe1 – xNbxO3 – δ

Perovskite-like oxides based on lanthanum–strontium ferrites are considered to be promising electrode materials for use in various types of fuel cells, and the strategy of modifying these materials by partial substitution of iron with highly charged ferroactive cations has proved to be an efficient way to increase their chemical stability. In this work, the results of a study of the permeability of microtubular oxygen membranes based on La_0.5Sr_0.5Fe_{1 –} _xNb_xO_{3 – δ} are presented for the first time. The activation energy of oxide bulk diffusion was found (20 ± 4 kJ/mol).
