摘要: Abstract A novel composite anion exchange membrane, zirconia incorporated quaternized polysulfone (designated as QPSU/ZrO 2 ), is prepared by solution casting method. The characteristic properties of the polymer membranes are investigated thermogravimetric analysis, X-ray diffraction and electrochemical impedance spectroscopy. morphology membrane observed SEM TEM studies. study an alkaline fuel cell (AMFC) operating with hydroxide ion conducting reported. Evaluation performed using electrode assemblies made up carbon supported platinum (Vulcan XC-72) anode cathode catalysts membrane. Experimental results indicate that AMFC employing a cheap non-perflourinated (QPSU/ZrO ) shows better performance. maximum power density 250 mW/cm for QPSU/10% ZrO at 60 °C. constitutes good candidate applications.
