New Type of Nanocomposite CsHPO-UiO-66 Electrolyte with High Proton Conductivity.

New (1−x)CsH2PO4−xUiO-66 electrolytes with high proton conductivity and thermal stability at 230−250 °C were developed. The phase composition and proton conductivity of nanocomposites (x = 0−0.15) were investigated in detail.
