Electrocatalytic activities of sputtered Pt films onto Y2O3-stabilized ZrO2 (YSZ) were studied for the propane combustion. Different temperatures and hold times of anodic polarization were essayed in order to verify the existence of permanent NEMCA effect on nanometric Pt films. The kinetic behavior of electrocatalytic activity exhibited temperature dependence, which could be related with the possible formation of PtOx species in the bulk of the Pt film during the anodic polarization
