Abstract:The development of rapid and dependable proton transport channels is crucial for proton exchange membrane fuel cells (PEMFCs) operating in low humidity conditions. Herein, an NH-Zr framework rich in basic sites was in situ constructed in a perfluorosulfonic acid (PFSA) solution, and PFSA-NH-Zr hybrid proton exchange membranes were prepared. The introduced NH-Zr framework successfully induced proton conducting groups (-SO3H) reorganization along the NH-Zr framework, resulting in the formation of fast ion transp… Show more
