Resumen:
The formic acid electrooxidation reaction was studied in a flow cell in 1 M HCOOH?0.5 M H2SO4 solution on apalladium film electrode. The evaluation of the open circuit potential (OCP) decay demonstrated that thespontaneous dehydrogenation of formic acid is quickly verified, leading to hydrogen adsorption and absorption.Moreover, the absence of carbon containing adsorbed species was verified by the application of voltammetricstripping after OCP and chronoamperometry. The results obtained demonstrate that the electrocatalyticoxidation of formic acid on Pd takes place through the spontaneous HCOOH dissociative adsorption with CO2evolution and the adsorbed hydrogen electrooxidation.
