Polarization Characteristics

Polarization characteristics of the hydrogen evolution reaction were studied at RuO2 Ru0.3Ti0.7O2 and Ru electrodes prepared by various methods. The initial activity of all oxide electrodes, related to the real surface area, was comparable. After a long-term cathodic loading of electrodes the change of physical-chemical properties occurred. Voltametric curves of electrodes showed that ad- and absorption of hydrogen occurred after a long-term cathodic loading. Absorbed hydrogen caused changes of RuO2 lattice parameters and even changes of lattice parameters of the Ti support on which the RuO2 layer was deposited. Arisen stresses in the Ru - oxides layers caused the destruction of the electrode layer and limited life-time of these electrodes.
