Stainless steel felt has been employed in AEMWE as a combination of oxygen evolution reaction (OER) electrocatalysts and porous transport layers, which are not only easy to prepare but also have excellent OER activity under alkaline conditions. However, by realizing detailed electrochemical analysis multi-scale visualization the bubble behaviors, it is found that combined effect chemical corrosion led constant accumulation metal oxides on stainless fiber surface post-durability compared slow-growing hydroxides after initial activation. Moreover, rougher morphology weaken hydrophilicity cause adjacent bubbles slower detach from electrode more likely fusion. The measured diameter leaving almost doubles, while total number decreases about two-thirds, causing increase plug flow field deteriorating performance long-term stability AEMWE.

Abstract Efficient and stable bifunctional catalysts for hydrogen oxygen evolution reaction play an important role in realizing economy. In this study, the multi‐heterogeneous interfacial catalyst, Ni 2 P@FeP@Co P (denoted as NFC), with asymmetric built‐in electric field is successfully designed synthesized. Benefiting from double charge balance effect, NFC exhibits superior (HER) (OER) catalytic activity. Importantly, NFC‐assembled anion‐exchange membrane (AEM) electrolyzer enhanced performance remarkable stability at industrial current densities high temperatures, reaching a density of 1000 mA cm −2 small voltage 1.95 V. The results dynamic X‐ray photoelectron spectroscopy tests indicate that self‐reconfiguration during OER provides additional active sites reaction. functional theory (DFT) demonstrate (BIEF) induces adaptive distribution charge, which optimizes adsorption desorption hydrogen/oxygen intermediates reaction, thereby enhancing kinetics overall water splitting process. This work presents novel strategies design highly energy conversion.
