Получение новых среднетемпературных протонных проводников на основе цирконата лантана-лития Li7-xHxLa3Zr2O12 методом ионного обмена

Abstract

Nowadays the process of searching for the new solid proton electrolytes with high proton conductivity at intermediate temperatures (200–600 oC) is actively developing due to the commercialization of fuel cell technologies. Here we present new materials with high proton conductivity that based on lithium lanthanum zirconate with the general chemical formula Li7-xHxLa3Zr2O12. New materials were made via an ion exchange process between lithium lanthanum zirconate Li7La3Zr2O12 and solutions of acids.
