Abstract

PEM Fuel Cells In article number 2503151, Yung-Eun Sung, Ki Ro Yoon, and co-workers showcase the development of ultrathin stretched PTFE nanofiber reinforcements via emulsification electrospinning and precision thermomechanical biaxial stretching. The resulting reinforced composite membranes demonstrate outstanding durability and efficiency, offering a promising route toward next-generation proton exchange membrane fuel cells with high power density and long-term operational stability.
