- An impedance spectroscopy cell and humidifier system has been developed to study the ion conducting properties and hydration/dehydration reactions in-situ during neutron powder diffraction experiments. As a model system, acceptor doped barium zirconate, BaZr0.5In0.5O2.75, has been studied during in-situ hydration and dehydration. Rietveld refinement of the collected data shows an increase in lattice parameter, a, upon hydration of BaZr0.5In0.5O2.75. In addition, we show the existence of a two-phase region, containing deuterated and non-deuterated barium zirconate, in the temperature interval ~ 573 K to ~ 873 K. Impedance spectroscopy data collected in-situ on heating and cooling and the corresponding ionic conductivity agree well with the change in deuteron content, as determined from neutron diffraction as a function of temperature. The newly developed in-situ cells make it possible to correlate conducting properties to structural changes under identical conditions and will have applicability to many other proton conducting solids.
