Protons (H ＋) are typically the carrier in hydrogen ion conduction. Numerous H ＋ conductors have been developed in a variety of systems, including oxides, polymers, and solid acids. Through the cation ...

The new material exhibits higher ionic conductivity than previously reported oxide solid electrolytes. The material is stable in air and has a wide operating temperature range of -10°C to 100°C. The ...
