In this study, PEEK was sulfonated with concentrated sulfuric acid (98%) at various degrees of sulfonation (DS) using sulfonation times between 2 and 5 h at a constant temperature of 50 °C. The properties and chemical structure of the sulfonated membranes (S-PEEK) were investigated using TGA, XRD, and FT-IR. In this study, the methanol permeability, thermal and mechanical properties, and proton conductivity of composite membranes were measured for the effect of Ferrierite zeolite as inorganic filler at various amounts (5,10,15,17, and 20% v/v). The proton conductivity and methanol permeability values of the composite membranes were measured compared to those of a commercial membrane, Nafion 117.
