Article Abstract

Hydrogen energy as the next-generation clean energy carrier has attracted the attention of both academic and industrial fields. A key limit in the current stage is the operation temperature of hydrogen fuel cells, which lies in the slow development of high-temperature and high-efficiency proton exchange membranes. Currently, much research effort has been devoted to this field, and very innovative material systems have been developed. The authors think it is the right time to make a short summary of the high-temperature proton exchange membranes (HT-PEMs), the fundamentals, and developments, which can help the researchers to clearly and efficiently gain the key information. In this paper, the development of key materials and optimization strategies, the degradation mechanism and possible solutions, and the most common morphology characterization techniques as well as correlations between morphology and overall properties have been systematically summarized.

Dynamic redistribution of intermediates induced by a local electric field microenvironment boosts efficient overall water electrolysis.

J Colloid Interface Sci

September 2025

State Key Laboratory of Heavy Oil Processing, College of Chemistry and Chemical Engineering, China University of Petroleum (East China), Qingdao 266580, China.

Reaction intermediates (RI) are key factors that directly determine the efficiency of the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). In this study, a local electric field microenvironment was built in a FeNi and MoNi heterostructure (H-FeNiMo/NMF) to induce the redistribution of hydroxyls and protons on the metal sites during the OER and HER. H-FeNiMo/NMF requires only 270 and 155 mV to reach 100 mA cm in alkaline media for OER and HER, respectively.

3D printing, as a versatile additive manufacturing technique, offers high design flexibility, rapid prototyping, minimal material waste, and the capability to fabricate complex, customized geometries. These attributes make it particularly well-suited for low-temperature hydrogen electrochemical conversion devices-specifically, proton exchange membrane fuel cells, proton exchange membrane electrolyzer cells, anion exchange membrane electrolyzer cells, and alkaline electrolyzers-which demand finely structured components such as catalyst layers, gas diffusion layers, electrodes, porous transport layers, and bipolar plates. This review provides a focused and critical summary of the current progress in applying 3D printing technologies to these key components.

Oxophilic Sites Mediated Dynamic Oxygen Replenishment to Stabilize Lattice Oxygen Catalysis in Acidic Water Oxidation.

Developing efficient and durable catalysts for the oxygen evolution reaction (OER) in acidic media is essential for advancing proton exchange membrane water electrolysis (PEMWE). However, catalyst instability caused by lattice oxygen (O) depletion and metal dissolution remains a critical barrier. Here, we propose an oxophilic-site-mediated dynamic oxygen replenishment mechanism (DORM), in which O actively participates in O-O bond formation and is continuously refilled by water-derived species.

Institute of New Energy Materials and Engineering, College of Materials Science and Engineering, Fuzhou University, Fuzhou, 350108 Fujian China.

Unlabelled: Proton exchange membrane water electrolyzers (PEMWEs) are a promising technology for large-scale hydrogen production, yet their industrial deployment is hindered by the harsh acidic conditions and sluggish oxygen evolution reaction (OER) kinetics. This review provides a comprehensive analysis of recent advances in iridium-based electrocatalysts (IBEs), emphasizing novel optimization strategies to enhance both catalytic activity and durability. Specifically, we critically examine the mechanistic insights into OER under acidic conditions, revealing key degradation pathways of Ir species.

The bioenergetic machinery of the cell is protected and structured within two layers of mitochondrial membranes. The mitochondrial inner membrane is extremely rich in proteins, including respiratory chain complexes, substrate transport proteins, ion exchangers, and structural fusion proteins. These proteins participate directly or indirectly in shaping the membrane's curvature and facilitating its folding, as well as promoting the formation of nanotubes, and proton-rich pockets known as cristae.
