Özet
Electricity generation from sustainable and renewable energy sources has become one of the key research priorities recently. Theincreasing investments in wind and solar power generation have highlighted the necessity of developing efficient energy storagetechnologies for smart grid systems and electric vehicle infrastructures. In this context, the need for more durable, environ-mentally friendly, and technically advanced energy storage systems has become increasingly important. Vanadium redox flowbatteries (VRFBs) represent one of the most promising large-scale energy storage technologies, attributed to their high efficiency,extended cycle life, and design versatility. A crucial element of VRFBs is the proton exchange membrane (PEM), which facilitatesproton transfer and directly affects the overall system performance. The elevated expense and restricted chemical stability ofcommercial membranes like Nafion have necessitated the search for alternative, cost-effective, and resilient materials. In thisstudy, a novel membrane with high proton conductivity, mechanical strength, and cost efficiency was developed as an alternativeto Nafion. Polyphenyl sulfone (PPSU), a thermally and chemically stable engineering polymer, was chemically sulfonated andfabricated into fibrous membranes using the electrospinning technique. The synthesized sulfonated PPSU (sPPSU) membranesdemonstrated an ion exchange capacity (IEC) of 2.1 meq g−1 and a proton conductivity of 1.68 × 10−2 S cm−1. These results indicatethat the developed sPPSU-based membranes provide a promising, durable, and cost-effective alternative as PEMs for fuel cellsand all redox flow battery applications.
