Abstract

The process of accelerated life test of an IrO₂/Ta₂O₅ coated titanium anode was monitored using cyclic voltammetry and electrochemical impedance spectroscopy. The vatiation with electrolysis time of anodic voltammetric charge Q^*, the double layer capacitance C_dl,the oxide film resistance R_f and the charge transfer resistance R_ct for oxygen evolution was measured. A deactivation mechanism was proposed based on the observation results.
