Hexagonal perovskite oxides: Electrolytes for next-generation protonic ceramic fuel cells

A new study presents a significant advancement in fuel cell technology. Researchers from Tokyo Tech identified hexagonal perovskite-related Ba5R2Al2SnO13 oxides (R = rare earth metal) as materials with exceptionally high proton conductivity and thermal stability. Their unique crystal structure and large number of oxygen vacancies enable full hydration and high proton diffusion, making these materials […]
