Facile cross-linking method for the fabrication of cross-linked membranes using highly sulfonated poly(arylene ether sulfone) and poly(ether ether ketone) for the proton exchange membrane fuel cell applications |
| 초록 |
Cross-linking method has been reported as an effective strategy to enhance the physicochemical stability of proton exchange membrane (PEM). However, the complex cross-linking procedure with multiple steps is one of the main impediments to widespread use of this technology. Here we present a simple and effective cross-linking method without the needs of additional polymer modification steps as well as catalysts or additives. The cross-linked membranes (CM-Xs) were successfully prepared by one stage of casting and heating the mixture solution containing sulfonated poly(ether ether ketone) (SPEEK) and sulfonated poly(arylene ether sulfone) (SPAES) in DMSO, where DMSO acts as a reagent and solvent simultaneously. The single cell performance of membrane electrode assembly (MEA) using CM-X with optimized cross-linking density showed a maximum power density of 0.70 W cm-2 at 80 ℃ under fully humidified H2/air condition. |
