Toughening of Y-doped BaZrO3 proton conducting electrolytes by hydration

In BaZr 1− x Y x O 3− x /2 (BZY), the state-of-the-art oxide proton conductors, the proton conductivity is facilitated by hydration of oxygen vacancies. Hydration induces lattice expansion, which may induce stress and thereby potentially reduce the mechanical integrity of fuel cells. Here, we report...
