Abstract
We have studied the electrical conductivity of rubidium and cesium acid salts of tungstophosphoric, tungstosilicic, molybdophosphoric, and molybdosilicic heteropolyacids. The materials have the form of hollow spheres up to 2 μm in size, and their surface layer is formed by nanoparticles. The ionic conductivity of the salts has been measured at different relative humidities (from 30 to 95%) in a wide temperature range (from–40 to 90°C). The highest conductivity is offered by the RbxH4–xSiW12O40 samples (σ = 5.3 × 10–4 S/cm at 30°C and 30% RH). Near 0°C, the materials undergo a phase transition which involves water crystallization and a change in activation energy, but their high proton conductivity persists even at negative temperatures.
