Rational Design of Multifunctional Nano–Architected Coatings for Bipolar Plates in Proton Exchange Membrane Fuel Cells

open access: yesRare Metals, EarlyView.
ABSTRACT Proton exchange membrane fuel cells (PEMFCs) require advanced bipolar plate coatings to enhance efficiency, durability, and commercialization potential. This review presents a systematic framework for evaluating and designing bipolar plate coatings, integrating material selection, performance metrics, deposition techniques, and future ...

Coalescence‐Ripening Mechanism of γ′−Ni3(Al, Ti) During Long‐Term/High‐Temperature Operation of Ni‐Based Superalloy Discs

open access: yesRare Metals, EarlyView.
ABSTRACT The evolution of the γ′−Ni3(Al, Ti) phase in superalloys is governed by a coupled coalescence‐ripening mechanism driven by elemental diffusion. In this study, thermal exposure experiments were performed at 750°C and 800°C for durations ranging from 100 to 20,000 h.

Multiscale Study of a Synergistic System in Carbon‐Coated Multimetal‐Based Selenides Toward Rapid and Highly Stable Sodium Storage

open access: yesRare Metals, EarlyView.
ABSTRACT The development of sodium‐ion batteries (SIBs) is limited by slow charge transfer kinetics and large material volume changes caused by the large radius of Na+. Leveraging the excellent physicochemical properties and unique heterostructures of metal selenides, ultrafine hetero‐CuFeSe2‐CoSe2 nanoparticles are in situ wrapped by ...
