• Normal pulse voltammetry
• Palladium

The kinetic parameters of formic acid oxidation on a carbon supported Pd electrode, such as the charge transfer coefficient (alpha) and apparent diffusion coefficient (D) are obtained by applying the technique of normal pulse voltammetry. The standard rate constant (k(o)) of formic acid oxidation on a Pd/C electrode is estimated. The results show that formic acid oxidation is more sensitive to temperature at relatively high potential because the activation energy is significantly increased as the potential rose above 0.6V.
