WitrynaA nanoscale polyamide (PA) layer was coated on the surface of Nafion-212 to fabricate a membrane, PA-c3-Nafion. PA-c3-Nafion was found to show ion conductivity 13.6% higher than that of a pristine Nafion-212 membrane at 80 °C, while providing improved mechanical performance and dimensional stability. Witryna10 kwi 2024 · The cell equipped with membrane embedded ZNs ran stably more than 550 cycles without significant performance degradation, which is much more than the commercial Nafion 212 membrane (∼120 cycles). This study provides an effective approach to defend against zinc dendrites and construct safe and efficient zinc-based … Witryna17 gru 2013 · In this paper, hydrogen permeation across two membranes (25-um-thick Nafion ® 211 and 18-um-thick reinforced composite membrane) are evaluated at … project management process group flow
