Synthesis of Ordered Mesoporous Carbon as Support for Pt-Co Alloys: Evaluation as an Alcohol-Tolerant ORR Catalyst for Direct Oxidation Fuel Cells

Autor: F.J. Rodríguez-Varela, N. M. Sanchez-Padilla, D. Morales-Acosta

Publikováno v: ECS Transactions. 61:39-47

In this work the Pt-Co/OMC as oxygen reduction reaction (ORR) cathode was evaluated under fuel-free and fuel-propanol in acid electrolyte conditions. By RDE measurements the ORR on the alloy seems to proceed via 4 e- transfer mechanism in acid media.
