dc.description.abstractThe electrochemical oxidation of methanol, 2-propanol, and their mixtures was investigated on a Pt/C thin film electrode in acid solution. It was confirmed that the oxidation of 2-propanol commences at less positive potentials than that of methanol and exhibits significantly higher oxidation current densities at low potentials. When both methanol and 2-propanol were present in the solution, the onset of the oxidation current was the same as for the oxidation of pure 2-propanol. Although both alcohols inhibit the oxidation reaction of each other to a certain extent, steady-state polarization measurements showed that their mixture provides higher current densities than single alcohols over the entire potential region from the hydrogen region to oxide formation on the Pt surface. This implies that the addition of 2-propanol into the fuel may extend the operational range of direct methanol fuel cells.en
dc.description.abstractIsptivana je elektrohemijska oksidacija metanola, 2-propanola i njihovih smeša na tankom filmu Pt/C katalizatora u kiseloj sredini. Potvrđeno je da oksidacija 2-propanola počinje na manje pozitivnim potencijalima nego oksidacija metanola i da daje znatno veće gustine struja pri nižim potencijalima. Kada su i metanol i 2-propanol prisutni u rastvoru, struja oksidacije se pojavljuje na istom potencijalu kao u slučaju čistog 2-propanola. Mada oba alkohola inhibiraju oksidaciju onog drugog u izvesnoj meri, stacionarma merenja su pokazala da njihova smeša daje veće gustine struja od pojedinačnih alkohola u celoj oblasti potencijala od vodonične oblasti pa do formiranja oksida na platini. To ukazuje da se radni opseg gorivog sprega sa metanolom može povećati dodatkom 2-propanola u gorivo.sr
