Abstract
The conductivity of mixtures of the solid electrolytes H3[PMo12O40]·13H2O and Cs2H[PW12O40] · 13H2O follows the predictions of the percolation theory, whereas the electrode impedance in the high frequency range fits well the model of double layer adsorption relaxation. It is concluded that both the adsorption relaxation and the reversibility of the electrodes are related to oxygen transfer, the oxygen ions being the minority charge carriers. Fast oxygen dispersion may occur at the polymer-solid electrolyte interface.
