VI Vernadsky National Academy of Sciences of Ukraine popup.description2  As a result of the studies, the fluoride-conducting phases Pb1-xLnxSnF4+x (Ln = Y, La, Ce, Nd, Sm, Gd), Ba1-xKxSnF4-x, Ba1-xYxSnF4+x, isotypic β-PbSnF4 were synthesized, and their structural features were established. regions of existence of individual phases, conducting properties were investigated. In all synthesized phases, fluorine anions charge transfer is provided by internodal fluorine anions, the concentration of which increases with increasing temperature. A method of manufacturing finely dispersed nanostructured electrocatalysts for fuel cells and electrolysers with a proton-conducting membrane based on iridium and platinum has been developed, which ensures a reduction in the specific consumption of platinum metals and improves the operational characteristics of both the fuel cell and the electrolyser with a proton-conducting membrane for the decomposition of water and the production of hydrogen and oxygen. Their properties were studied and operational characteristics were determined. Highly active alloys based on aluminium have been developed to generate hydrogen by chemical decomposition of water at room temperature. The created scientific and technical solution has the prospect of practical use in hydrogen generators of the hydrolysis type of different performance, for supplying hydrogen-oxygen fuel cells with hydrogen at room temperature. A method of high-temperature electrochemical synthesis of catalysts based on composite nanopowders of tungsten carbides for electrolytic hydrogen generators has been developed. The conducted studies confirm the prospect of using tungsten carbide as a catalytically active electrode material for obtaining hydrogen in an acidic environment. The methodology for the synthesis of oxide composites based on cobalt, manganese, zirconium, and cerium oxides was developed and their activity in the decomposition of hydrogen peroxide was determined.
