      abstract     = {Solid oxide fuel and electrolysis cells (SOFC/SOEC) based
                      on ceramic proton conductors efficiently convert chemical
                      energy into electricity and vice versa at intermediate
                      operating temperatures (400-600 °C)[1]. Acceptor doped
                      BaCeO3 and BaZrO3, are the most extensively studied proton
                      conductors. BaCeO3 exhibits high proton conductivity but
                      shows lower chemical stability in H2O and CO2 environments.
                      Conversely, BaZrO3 possesses higher chemical stability but
                      lower proton transport ability at the grain boundaries[2].
                      Preparing Ba(Zr,Ce)O3 solid solutions with the appropriate
                      Zr/Ce ratio at the B-site in the perovskite crystal
                      structure is a compromise strategy. In this work, 20
                      $mol.\%$ of Ce was introduced into the lattice of Y-doped
                      BaZrO3, and 0.5 $wt.\%$ of NiO was applied as a sintering
                      aid. The Y2O3 substituent amount varies within the range of
                      10-30 $mol.\%$ in order to study the influence of Y on the
                      phase formation, microstructure, hydration behavior and
                      electrical performance. Y-riched phase has been found in
                      samples with Y content exceeding 25 $mol.\%.$ And excessive
                      Y2O3 substitution has a negative impact on the grain
                      boundary conductivity. In addition, mechanical performance
                      and thermo-chemical stability is also taken into
                      consideration to evaluate the suitability of this material
                      for electrochemical devices.},
