Morphological and Structural Aspects of Electrochemical Catalysis of Oxygen Reduction with the Cobalt Complex of Sodium Pectate

Abstract

Catalysts for oxygen reduction (OR) based on cobalt complexes of sodium pectate have been developed, which are interesting from the viewpoint of application in proton-exchange membrane fuel cells. The catalysts were studied by electrochemistry and electron microscopy. The catalyst with 15% Co²⁺ cations substituted for sodium ions was found to be most efficient.
