Study Suggests New Criteria For Electrocatalysts

Theoretical findings on O2 reduction energetics should help the selection of better-performing fuel-cell catalysts
Department: Science & Technology

Key factors dictating the energetics of fundamental electrocatalytic reactions, such as the oxygen reduction reaction that takes place in most fuel cells, have gone unnoticed, according to a theoretical investigation by Feng Tian and Alfred B. Anderson of Case Western Reserve University (J. Phys. Chem. C, DOI: 10.1021/jp1100126). The study suggests new criteria for selecting better-performing catalysts for fuel cells and other electrochemical systems. A central problem limiting fuel-cell performance and . . .
