Surface and electrochemical properties of the dimensionally stable anode Ti/(Ru0.3Ti0.7)O2 were studied as a function of the annealing temperature using different conditions in order to perform the cooling process of the oxide films (conventional thermal shock and the slow cooling processes). It was found that surface and electrochemical properties for the oxygen evolution reaction are both affected through the cooling process, being the electrode prepared at 400 ºC using the slow cooling process the less susceptible to wear. The Tafel slope obtained in the high overpotential domain was analysed in light of the apparent charge transfer coefficient.
