A Promising Proton Conducting Electrolyte BaZrHoO (0.05 ≤ x ≤ 0.20) Ceramics for Intermediate Temperature Solid Oxide Fuel Cells.

In this study, the Ho-substituted BaZrO electrolyte ceramics (BaZrHoO, 0.05 ≤ x ≤ 0.20) were synthesized through a low-cost flash pyrolysis process followed by conventional sintering.
