Anion exchange membrane fuel cells (AEMFCs) have experienced rapid advancement in the past few years due to the discovery of high-performance AEMs and ionomers. Here, we report a series of side-chain-type poly(dibenzbeyl-co-terphenyl piperidinium) (s-PDTP) copolymers as ionomers and membranes for AEMFC applications. The features of aryl ether-free PDTP polymer backbone and pendent ammonium groups endow both high alk. stability and excellent micromorphol. to s-PDTP copolymers. These ion-exchange-capacity (IEC)-controlled s-PDTP membranes possess high OH- conductivity >120 mS cm-1 at 80 °C, reasonable mol. weight (Mw = 150-290 kDa), and excellent ex-situ durability in 1 M NaOH at 80 °C for 1000 h (∼90% conductivity remaining). For ionomer research, s-PDTP ionomers with moderate IEC (∼3.0 mmol g-1) and rational water uptake (∼200%) exhibit optimal AEMFC performance based on a PDTP membrane compared to high-IEC or low-IEC s-PDTP ionomers (>3.4 mmol g-1 or <2.4 mmol g-1). Based on Pt/C, s-PDTP-based AEMFCs reach a peak power d. (PPD) of 1.47 W cm-2 in H2-O2 and 1.04 W cm-2 in H2-air (CO2-free) at 80 °C. The results came from multiple reactions, including the reaction of 1-Methyl-4-piperidone(cas: 1445-73-4Application of 1445-73-4)
1-Methyl-4-piperidone(cas: 1445-73-4) is a member of piperidine. Piperidine is a key saturated heterocyclic scaffold found in several of the top-selling small molecule pharmaceuticals and natural alkaloids, with a diverse range of biological activities. Hence, continuous efforts have been made to develop convenient methods to prepare piperidine derivatives.Application of 1445-73-4
