Unveiling distribution of defects in proton conductors

Researchers have developed a new idea to improve proton conductivity in rare-earth doped BaZrO3 to be used as an electrolyte material in intermediate temperature solid oxide fuel cells (IT-SOFCs). The team suggests that a key to liberate trapped protons, which are the cause of low proton conductivity at the intermediate temperature range, is to introduce the appropriate amount of oxygen vacancies that cause repulsive interaction with protons.
