Currently, attention has been paid toward expanding the electrochemically active surface area (ECSA) of catalysts and increase their intrinsic activity in the oxygen reduction reaction (ORR). However, despite innumerable efforts having been carried out to explore this possibility, most of these achievements have focused on the rotating disk electrode (RDE) in half-cells, and relatively few results have been adaptable to membrane electrode assemblies (MEAs) in full-cells, which is the actual operating condition of fuel cells. Thus, it is uncertain whether these advanced catalysts can be used as a substitute in practical fuel cell applications, and an improvement in the catalytic performance in real-life fuel cells is still necessary. Therefore, from a more practical and industrial point of view, the goal of this review is to compare the ORR catalyst performance and durability in half- and full-cells, providing a differentiated approach to the durability concerns in half- and full-cells, and share new perspectives for strategic designs used to induce additional performance in full-cell devices. ？ English American Chemical Society Differences in the Electrochemical Performance of Pt-Based Catalysts Used for Polymer Electrolyte Membrane Fuel Cells in Liquid Half- And Full-Cells Article 10.1021/acs.chemrev.0c01337 1 Chemical Reviews, v.121, no.24, pp.15075 - 15140 Chemical Reviews 121 24 15075 15140 N scie scopus 000754615100005 2-s2.0-85118669391 Chemistry, Multidisciplinary Chemistry Review PROTON-EXCHANGE-MEMBRANE OXYGEN REDUCTION REACTION RAY-ABSORPTION SPECTROSCOPY GAS-DIFFUSION LAYER NONCARBON SUPPORT MATERIALS ALIGNED CARBON NANOTUBES THIN-FILM CATALYSTS TIME-RESOLVED XAFS CATHODE-CATALYST ULTRA-LOW 전기화학 연료전지 촉매 전극 MEA
