ABSTRACT=<p>A new kind of electrochemical catalyst based on a Pt porous catalyst film deposited on a β″-Al<sub>2</sub>O<sub>3</sub> ceramic Ag<sup>+</sup> conductor was developed and evaluated during propane oxidation. It was observed that, upon anodic polarization, the rate of propane combustion was significantly electropromoted up to 400%. Moreover, for the first time, exponential increase of the catalytic rate was evidenced during galvanostatic transient experiment in excellent agreement with EPOC equation.</p>
