“…The apparent morphology and the microscopic phase separation of the membranes are the key conditions for judging its densification as well as ion transport. ,, The overall yellowish-green color and transparency can be seen through the pictures of the membranes taken in Figure a. As can be seen in Figure b–d, the membrane is very flexible and maintains good integrity after vigorous kneading.…”

At present, in order to expand and extend the application scope of anion-exchange membrane fuel cells (AEMFCs) in response to the global development of green energy, the design and development of anion exchange membranes (AEMs) that combine high electrochemical performance and long life is a matter of great urgency. In this paper, a series of QPTPTMT-x AEMs with different contents of 2,2,2-trifluoro-1-(5-methoxythiophen-2-yl)ethan-1-one (TMTE) were prepared by first synthesizing TMTE monomers and then introducing them into the polyaryl piperidine skeleton via an ultrastrong acid-catalyzed reaction. With the introduction of TMTE monomers, the F atom provides strong hydrophobicity, while the S heteroatom is present to facilitate intermolecular interactions. On the other hand, –CF3 and O atoms interact together with cations to produce dual cation–dipole interactions. The comprehensive performance of QPTPTMT-x AEMs produces great improvement. Particularly, QPTPTMT-20 AEM with the lowest ion-exchange capacity and swelling ratio achieved the best ionic conductivity of 180.1 mS cm–1 at 80 °C while possessing a tensile strength of 72 MPa. After immersion in 3 M NaOH for 1080 h, the conductivity retention of the AEMs was still 94.4%. Last, the membranes were prepared into membrane electrode assemblies for single-cell performance testing. The QPTPTMT-20 AEM demonstrated a peak power density of 416 mW cm–2 at 80 °C.

“…All these types will follow the same working principle for energy production with different operating temperatures and efficiencies in energy production. High power density, operating conditions at low temperature, and easy scale-up features project this polymer electrolyte fuel cell to be highly efficient, more than the others. , Proton exchange membrane fuel cells (PEMFCs) and anion exchange membrane fuel cells (AEMFCs) , are the types of polymer electrolyte fuel cell that transports selective ions like protons and anions like OH – and Cl – with generation of electricity. Though AEMFCs subside the disadvantages caused by PEMFCs like carbon monoxide poisoning, the high cost of noble metal catalysts, and complex water management, it lacks in proton conductivity when compared to the state-of-the-art Nafion which turns on light toward the development of PEMFCs. , …”

Proton exchange membrane fuel cells (PEMFCs) are a highly efficient energy producing device that stands as a novel approach to sort out the energy demand faced by the world. The proton exchange membrane plays a significant role for the function of PEMFCs. Possessing dual functional behavior for ease of proton transfer which other aromatic polymers fail to own naturally has made the triazole moiety a unique PEM material. The material’s elevated self-dissociation capability, facilitating proton conduction, coupled with its high dielectric constant led to an increased demand for its application, highlighting its significance in various usage scenarios. For instance, by self-diffusion, 1H-1,2,3-triazole and 1H-1,2,4-triazole materials exhibited conductivities of 1.3 × 10–4 and 1.5 × 10–4 S/cm, respectively, in their pure forms. Various research groups utilize the triazole molecule as an ionic cross-linker, as a source for the introduction of functional groups, and as a dopant that eventually increases the proton conductivity. This review focuses on the advantages and different proton conduction processes that have been carried out in triazole materials like 1H-1,2,3-triazole, 1H-1,2,4-triazole, poly(1-vinyl-1,2,4-triazole), and the new originating sulfonated polytriazole.
