Anion exchange membrane fuel cells (AEMFCs) have attracted extensive attention in the recent years, primarily due to distinct advantage potentials they over mainstream proton cells. The anion (AEM) is key component of AEMFC systems. Because unique characteristics water management AEMFCs, understanding mobility through AEMs for this technology, as it significantly affects (and limits) overall cell performances. This work presents a study equilibrium state and kinetics uptake (WU) exposed...

Abstract There is a need to understand the water dynamics of alkaline membrane fuel cells under various operating conditions create electrodes that enable high performance and stable, long-term operation. Here we show, via operando neutron imaging micro X-ray computed tomography, visualizations spatial temporal distribution liquid in cells. We provide direct evidence for accumulation at anode, which causes severe ionomer swelling loss, as well cell dryout from undesirably low content...

Abstract The normal operation of lithium‐ion batteries (LIBs) at ultralow temperature (&lt;−40 °C) is significant for cold‐climate applications; however, their plagued by the low capacity conventional intercalation cathodes due to sluggish kinetics and slow solid diffusion Li + in frameworks. Here, it demonstrated that amorphization an effective strategy promote low‐temperature dynamics relieving blocking effect a dense lattice structure on ion transport under cryogenic conditions. As...

Anion exchange membrane water electrolyzer (AEMWE) is a rising technology that offers potential advantages in cost and scalability over proton (PEMWE) technology. However, AEMWEs stably operate pure still employ platinum-group-metal (PGM) catalysts, especially at the cathode. Here, by using an appropriate ionomer both anode cathode, as well new hydrogen evolution reaction (HER) catalyst, we achieve sustained pure-water AEM electrolysis only PGM-free electrocatalysts. Our optimized AEMWE can...

Under pathological conditions, the joint is not well lubricated, which inevitably leads to osteoarthritis. Currently, in clinics injection of hyaluronic acid (HA) as an intra-articular viscosupplement one main methods for alleviation However, viscosity HA reduces dramatically under high shear rate due shear-thinning effect. Therefore, it crucial enhance lubrication property order treat osteoarthritis effectively. In this study, we successfully grafted 2-methacryloyloxyethyl phosphorylcholine...
