Mass changes of electrodes containing MnO2 during charging and discharging processes were studied using QCMB techniques. The process is accompanied by reversible uptake of water and insertion of H3O+ insted of H+ should be expected.

Pomocí QCMB byly studovány změny hmotnosti při nabíjení a vybíjení elektrod obsahujících MnO2. Redukce těchto elektrod je provázena vratnou sorbcí vody a lze předpokládat, že probíhá jako inserce iontů H3O+ a nikoli protonů H+. (cs)
