Abstract
Perovskite-like oxides based on lanthanum-strontium ferrites are considered 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 proven to be an effective way to increase their chemical stability. In this paper, for the first time, the results of a study of the permeability of microtubular oxygen membranes based on La0.5Sr0.5Fe1 – xNbxO3 – δ oxide are presented. The activation energy of oxide bulk diffusion (20±4 kJ/mol) was found.
