Summary: In this study, nanocomposite polyelectrolyte membranes based on sulfonated polystyrene (SPS) and imidazole-2-acetic acid (Im) blend (SPSIm), incorporated with halloysite nanotubes (HNTs), were investigated for direct methanol fuel cell (DMFC) applications. The optimal degree of sulfonation for PS was selected based on hydrolytic stability, and SPS was blended with Im to improve proton conductivity and decrease methanol permeability. The addition of HNTs further reduced methanol crossover by introducing tortuous diffusion pathways. The resulting SPSIm/HNT membrane showed significantly decreased methanol permeability and improved membrane selectivity parameter, making it a potential candidate for DMFC applications.

Summary: Coupling-type sulfonated poly(phenylquinoxaline) (c-SPPQ) with side chain and main chain sulfonic acid groups was synthesized through post-sulfonation. Proton exchange membranes made from c-SPPQ exhibited good performance, including low methanol permeability, high methanol tolerance, and good mechanical properties due to acid-base interaction of sulfonic acid and phenylquinoxaline groups. The superior conductivity and low methanol permeability of c-SPPQ make it a promising material for direct methanol fuel cells.
