“…Polymer-based materials are deemed to be excellent materials for BPs owing to their good mechanical properties, corrosion resistance, low cost and ease of processing. Poly(methyl methacrylate) (PMMA), PVDF, PET, poly(styrene-co-acrylonitrile), nylon 6, polystyrene, poly(vinyl acetate), etc., have been used to prepare BPs for PEMFCs [4]. However, the addition of high concentrations of conductive fillers is required to ensure electrical conductivity and this leads to poor mechanical properties and machining problems.…”
