Casting Membrane of Acrylamide/Polymethacrylic acid and Reinforced by PAC for Application in Fuel Cell Unit

Abdel-Hady EE, El-Toony MM and Abdel-Hamed MO

Gamma irradiation poses very important role for casting the polymer membranes. Acrylamide was hydrolyzed by phosphoric acid, while it plays a potential role for coordination of poly methacrylic acid and hydrolyzed acrylamide (acrylic acid) around them. Adding PAC in different ratios for membrane reinforcement besides adsorbing excess of hydrogen proton in aqueous media which enhances proton conductivity. Thermal characterization of the membranes was carried out using thermal gravimetric analysis, while their mechanical properties were investigated by measuring hardness and Chemical description was discussed by studying FTIR and ion exchange capacity (IEC). Morphological characteristics were performed by scan electron microscope. Crystallinity was reviewed using X-ray diffraction which attempts the homogeny of the casted membrane. Electrical resistivity of the membrane was measured resulted in 7 ohm/cm while it reduced to 2.7 ohm by temperature rising to 80°C which confirmed the availability of the membrane in fuel cell usage.
