Preparation and Performance Evaluation of SPEEK/Polyaniline Composite Membrane for Direct Methanol Fuel Cell

Abstract
Polymer composites comprising sulfonated poly(ether ether ketone) (SPEEK) and 10 to 50 wt% of Poly(trimellitic anhydride chloride-co-4,4′-methylenedianiline) (PTCMA) were prepared by solution casting. The effects of PTCMA concentrations on morphological, thermal and transport properties (water uptake, methanol permeability, ion exchange capacity and proton conductivity) were investigated. A morphological analysis revealed an homogenous dense microstructure for all the composites. Also, transport property tests revealed that the water uptake, methanol permeability and ion exchange capacity were enhanced by the addition of PTCMA whereas proton conductivity deteriorated. As shown by a thermogravimetric analysis, the difference between the thermal properties of the pure SPEEK and the composites was insignificant. Overall, the composites were observed to display a better global performance in terms of transport properties than pure SPEEK.
