| Popis: | One of the most rapidly developing directions in the field of alternative energy sources is hydrogen energetics. Fuel cells, the main component of which is a proton-exchange membrane, facilitate the direct conversion of chemical energy into electrical energy. Superprotonic crystals are promising materials for the creation of proton-exchange membranes of fuel cells and other electrochemical. Multicomponent water–salt growth systems are studied in order to obtain new superprotonic crystals MmHn(AO4)(m + n)/2 ⋅ yH2O (M = K, Rb, Cs, NH4, AO4 = SO4, SeO4, HPO4) and modify the properties of known compounds. The conditions for the growth of a number of new superprotonics are found, and the relationships between their structure and properties are studied. |
