Abstract The performance of alkaline fuel cells is severely limited by substandard anion exchange membranes (AEMs) due to the lower ionic conductivity compared proton membranes. AEMs can be effectively improved regulating microphase structure, but it still cannot meet practical use requirements. Here, enhanced microphase‐separated structures are constructed cooperativity highly hydrophilic dual cations and hydrophobic fluorinated side chains. Meanwhile, introduction O enhances flexibility...
Abstract C60‐cored star polyfluorenes were synthesized and fully characterized. A high yield (81%) hexakisaddition of C60 was developed by using Prato reaction bulky fluorene addends. Suzuki polycondensation the hexakisadducts carrying six 2‐bromofluorene addends AB‐type monomer (2‐bromo‐9,9‐dioctylfluorenyl‐4,4,5,5‐tetramethyl‐ [1,3,2]‐dioxaborane) with Pd(PPh 3 ) 4 as catalyst precursor afforded desired polyfluorenes. Their three‐dimensional structure can effectively reduce aggregation...
The activity of the catalyst layer is crucial for performance alkaline anion exchange membrane fuel cells (AEMFCs). However, microscopic transport mechanism active species (gas, H2O, OH - ) in triple-phase boundary (TPB), which composed gas, liquid, and solid particles, has not yet been elucidated so far. Herein, quaternized polyphenylene oxide (PPO) ionomers with different hydratability are synthesized characterized by electrochemical analysis molecular dynamics simulations. results...
