Summary: Commercially available Pt/C catalysts used in PEMFCs suffer from insufficient triple-phase boundary formation and carbon oxidation, leading to shortened lifetime and efficiency. To address this issue, a new class of carbon-free electrocatalysts was developed by dispersing Pt nanoparticles on ZrP nanoplates. The Pt/ZrP electrocatalyst showed improved durability and 4.6 times higher mass activity compared to Pt/C. Single-cell level validation demonstrated achievable current densities of 0.600, 0.890, and 0.890 A cm(-2) for ZrP@Pt, Pt/ZrP, and Pt/C, respectively, in PEMFC.

Summary: A high-performance electrocatalyst Pt/3DNG for PEMFC applications has been developed by grafting an active triple-phase boundary on the 3DNG support material to precisely control the formation of the proton conducting ionomer interface at the active sites. Introducing the concept of in situ generation of the proton conducting-ionomer based active triple-phase boundary during electrode fabrication could potentially replace the conventional method of using Nafion ionomer for electrode preparation.

Summary: Designing highly active and bifunctional oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) catalysts with non-noble metals such as Fe/Co/Ni on MXene surfaces has shown superior performance compared to traditional unifunctional catalysts, providing a novel pathway for tunable catalytic behavior in MXenes. The electronic structure analyses revealed that the excellent catalytic activities in MXene-based DACs are attributed to the electron-capturing capability and synergistic interactions between Fe/Co/Ni adsorbents and MXene substrate. These findings not only suggest promising candidates for MXene-based bifunctional ORR/OER catalysts but also offer new theoretical insights into rationally designing noble-metal-free bifunctional DACs.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
