The present work describes a novel process for the elaboration of ceramic material. Y-doped barium zirconate, an electrolyte material Protonic Ceramic Fuel cell, was synthesized by continuous hydrothermal in supercritical conditions (410 °C/30.0 MPa) using nitrate precursors and NaOH reactants. use water allowed formation particles about 50 nm diameter with narrow size distribution. X-Ray Diffr...

The acceptor-doped BaZrO3 (BZY) shows considerable bulk proton conductivity. However, the higher grain boundary (GB) resistances significantly limit overall transport of protons in polycrystalline samples. fundamental questions about diffusion mechanism at defects are still unclear. By performing detailed density functional theory (DFT) calculations, we have studied properties GB, where presenc...
