Proton conductivity of Li⁺–H⁺ exchanged Li₇La₃Zr₂O₁₂ dense membranes prepared by molten long-chain saturated fatty acids

Abstract

Alkali-proton-exchanged oxides have broad potential as proton-conducting solid-state electrolytes for fuel cells and electrolyzers. However, materials in this class have not been widely explored because of the difficulty in preparing...
