In this work, structural characterization of selected perovskite-type compounds from Ba[Formula: see text]Gd[Formula: see text]Zr[Formula: see text]SnxInyO[Formula: see text] group is given, including high temperature XRD measurements. An evidence of water incorporation into the crystal structure of the materials in a form of OH[Formula: see text] is discussed on a basis of thermogravimetric studies, with mass spectroscopy analysis of the gases released from samples on heating/cooling. As expected, oxygen non-stoichiometry was found to play a dominant role concerning possibility of water uptake. In addition, a rather strong affinity of the materials towards CO2 was documented, which seems to be a problem concerning possible application of the compounds as proton conducting solid electrolytes.
