Conductivity of Gd-doped BaCeO3 protonic conductor in H2-H2O-O2 atmospheres
(2013)This work proposes a radically new simple method of evaluation of the proton conductivity based on measurement of the conductivity of ceramic materials depending on the oxygen partial pressure (pO2) at a gradual transition ... -
Effect of dopants on CeO2 based solid state electrolytes for intermediate temperature electrochemical devices
(2011)The present work aims at the investigation of the influence of different dopants' ionic radii and their concentration on both the lattice parameters and the density of Ce1-xLnxO2-δ (x = 0-0.20; Ln = La, Nd, Sm, Eu, Gd, Dy, ... -
