The organic - inorganic complete membranes were prepared with the incorporation of high proton conducting functional particles into Sulfonated poly(ether ether ketone) (SPEEK). The organic phase consisted mainly of SPEEK with different degree of sulfonation. The inorganic phase was limit with one or two functional particles that can improve the performance of membrane towards fuel cell proton exchange membrane application. The new composite membranes was designated as SPEEK-CM(F)s. The incorporation of functional particle was ascertained by Fourier transform infrared spectroscopy and X-ray diffraction analysis. SPEEK-CM(F)s were characterized for their thermal and physical properties. The membrane stability, i.e. liquid uptake in water and in aqueous methanol solution, oxidative stability as well as mechanical and thermal stability were tested. SPEEK-CM(F)s posses characteristics as the promising electrolyte in direct methanol fuel cells.
