In 2022,Wu, Xingyu; Chen, Nanjun; Klok, Harm-Anton; Lee, Young Moo; Hu, Xile published an article in Angewandte Chemie, International Edition. The title of the article was 《Branched Poly(Aryl Piperidinium) Membranes for Anion-Exchange Membrane Fuel Cells》.HPLC of Formula: 1445-73-4 The author mentioned the following in the article:
Anion-exchange membrane fuel cells (AEMFCs) are a promising, next-generation fuel cell technol. AEMFCs require highly conductive and robust anion-exchange membranes (AEMs), which are challenging to develop due to the tradeoff between conductivity and water uptake. Here we report a method to prepare high-mol.-weight branched poly(aryl piperidinium) AEMs. We show that branching reduces water uptake, leading to improved dimensional stability. The optimized membrane, b-PTP-2.5, exhibits simultaneously high OH- conductivity (>145 mS cm-1 at 80 °C), high mech. strength and dimensional stability, good processability, and excellent alk. stability (>1500 h) in 1 M KOH at 80 °C. AEMFCs based on b-PTP-2.5 reached peak power densities of 2.3 W cm-2 in H2-O2 and 1.3 W cm-2 in H2-air at 80 °C. The AEMFCs can run stably under a constant current of 0.2 A cm-2 over 500 h, during which the b-PTP-2.5 membrane remains stable. In the experiment, the researchers used 1-Methyl-4-piperidone(cas: 1445-73-4HPLC of Formula: 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.HPLC of Formula: 1445-73-4
