Zirconium hydrogen phosphate / sulfonated poly (arylyene ether) s composite membranes has been prepared and evaluated by the unit cell test for direct methanol fuel cell (DMFC) applications. The comparison between the performances of zirconium hydrogen phosphate/ sulfonated poly (arylyene ether) s composite membranes and Nafion 115 shows that the unit cell performance with composite membrane was superior to that of Nafion, which makes zirconium hydrogen phosphate/ sulfonated poly (arylyene ether) s composite membrane a potential candidate for direct methanol fuel cells.

Methanol crossover through a polymer electrolyte membrane has numerous negative effects on direct methanol fuel cells (DMFCs) because it decreases the cell voltage due to a mixed potential (occurrence of both oxygen reduction and methanol oxidation reactions) at the cathode, lowers the overall fuel utilization and contributes to long-term membrane degradation. In this work, an investigation of methanol transport properties of composite membranes based on sulfonated polysulfone (sPSf) and modified silica filler is carried out using the PFG-NMR technique, mainly focusing on high methanol concentration (i.e., 5 M). The influence of methanol crossover on the performance of DMFCs equipped with low-cost sPSf-based membranes operating with 5 M methanol solution at the anode is studied, with particular emphasis on the composite membrane approach. Using a surface-modified-silica filler into composite membranes based on sPSf allows reducing methanol cross-over of 50% compared with the pristine membrane, making it a good candidate to be used as polymer electrolyte for high energy DMFCs.
