The Effect of Zn Addition to La1−xSrxScO3−δ Systems as a B-site Dopant

Abstract

Zn was introduced to La1−xSrxScO3−δ as a B-site dopant. The addition of Zn markedly improved the sinterability of the material, and a dense sinter could be synthesized by a solid-state reaction method. Although conductivity was slightly decreased by the addition of Zn, it was shown that La1−xSrxSc1−yZnyO3−δ is a useful electrolyte material for intermediate-temperature fuel cells.

Novel co-doped protonic conductors BaLa1.9Sr0.1In1.95M0.05O6.925 with layered perovskite structure

“…One of the known ways to improve the conductivity is by co-doping of cationic sublattices of complex oxides. This method has been successfully applied to well-known proton conductors such as barium cerate-zirconates [17][18][19][20][21][22] and lanthanum scandates [23][24][25][26]. At the same time, the possibility of applying this method to a new class of proton-conducting materials, such as layered perovskites AA′nBnO3n+1 [27], is currently under investigation.…”
