Abstract
Polymeric membrane nanocomposites incorporating phosphotungstic acid in a sulfonated poly(arylene ether sulfone) matrix were synthesized as candidates for fuel cell proton exchange membranes. The main goal of this research is to improve upon purely polymeric proton exchange membranes and allow the fuel cell to be run at temperatures greater than 100°C. The phosphotungstic acid serves to improve the protonic conductivity of the membrane while decreasing the water absorption. This is a surprising result, as with most sulfonic acid-base membranes, protonic conductivity has been directly related to membrane water content. In addition, the inorganic filler also improves the modulus of the material.
