Oxidation of formate on hydrogen-loaded palladium

Hydrogen occluded in palladium assists in the electrooxidation of formate ions at its surface, by chemically reacting with strongly adsorbed poisoning species and contributing to their release fromthe surface. Reaction between em erging occluded hydrogen and adsorbed CO regenerates surface sites for the continuous electrochemical oxidation of formate ions. ? 2001 International Association for Hydrogen Energy.
