A composite membrane for proton exchange membrane fuel cell application was
fabricated by blending SPSEBS(Sulfonated Poly Styrene Ethylene Butylene Poly
Styrene) with Boron Phosphate. The effects of Boron Phosphate and its relative loading
were analyzed in terms of IEC and proton conductivity. Water and methanol uptake of
these membranes were also studied.
The synthesized polymer composite membrane was characterized by IR
spectroscopy. Thermal stability was studied by using TGA, DSC and DMA analyses.
Surface morphology was done by scanning electron Microscopy (SEM) and XRD studies
indicated the existence of a certain level of crystallinity in the SPSEBS, as well as the
composite membrane. Mechanical strength of the membranes was measured by Universal
