dc.description.abstractABSTRACT: Membranes are a key component of electrochemical devices such as fuel cells and electrolyzers. Nafion® membranes, considered the industry-standard benchmark, exhibits several performance limitations which has fostered research for better membranes.1-3 Alternative membrane improvements are driven by the need to lower production costs and improve ion transport, chemical and thermal durability along with controlling excessive swelling and gas crossover. In this work, new membranes based on poly(etheretherketone) (SPEEK) polymer were prepared by the addition of polyvinylidene fluoride (PVDF) and the incorporation of graphene oxide with bisphosphonic acid functionalities (GOBP) as a dopant. The new membranes are characterized and their properties evaluated, showing improved proton conductivity and chemical durability.eng
