Influence of the Pore Structure on the Activity and Stability of Non-precious Metal Catalysts for Proton Exchange Membrane Fuel Cells
Abstract The activity/performance of non-precious metal catalysts for the oxygen reduction reaction (ORR) in fuel cells is critically dependent on the pore structure of the catalyst layer, but a systematic understanding of how micropores and mesopores affect activity and stability remains limited. In this work, we empl...
