Abstract: The current of COoxidation at the Nafion-Pt hydrophobic electrode is higher in 0.5 mol/L H2SO4than in 1mol/L NaOH and decays with time over a few hours till reaching a steady state. These observation can be explained in terms of the ion-selectivity of Nafion and the Limited transport rate of water across the membrane.

Key words: Oxidation of carbon monoxide, Nafion membrane, Hydrophobic gas diffusing electrode
