摘要
The paper discusses the features of proton transport in isovalently doped layered perovskites based on barium-lanthanum indate BaLaInO4. The effect of the nature and concentration of the dopant on the unit cell size, water absorption, and proton conductivity was estimated. It is shown that the doping of the cationic sublattices of the layered perovskite BaLaInO4 with Nd3+, Gd3+, Pr3+, In3+, Y3+ ions makes it possible to increase the proton conductivity up to ~ 2 orders of magnitude, and the complex oxides obtained by this method are promising from the point of view of their further study as a material for a proton-conducting solid oxide electrolyte fuel cell.
