This paper presents the investigation of a novel material, SrLa2Sc2O7, as a protonic conductor. The results demonstrate that SrLa2Sc2O7 exhibits high protonic conductivity and water uptake ability, making it a potential electrolyte for solid oxide fuel cells and electrolyzers.
Novel materials with target properties for different electrochemical energy conversion and storage devices are currently being actively created and investigated. Materials with high level of protonic conductivity are attracting attention as electrolytes for solid oxide fuel cells and electrolyzers. Though many materials are being investigated as potential electrolytic components for these devices, many problems exist, including comparability between electrodes and electrolytes. In this paper, layered perovskite SrLa2Sc2O7 was investigated as a protonic conductor for the first time. The possibility for water uptake and protonic transport was revealed. It was shown that the SrLa2Sc2O7 composition can be considered a prospective ionic conductor. The layered perovskites can be considered as very promising materials for electrochemical devices for energy applications.
