Membrane characterization was performed by SEM, FTIR, and thermogravimetric analyses. The performance of AEMs was evaluated by water uptake, swelling degree, ion exchange capacity, OH - conductivity, and single cell tests. A combination of quaternized ammonium poly(vinyl alcohol ) (QPVA) and poly(diallyldimethylammonium chloride) (PDDMAC) showed the highest conductivity, water uptake, and swelling among other functional group sources. The AEM with a combined mass ratio of QPVA and PDDMAC of 1:0.5 (QPV/PDD 0.5 ) has the highest hydroxide conductivity of 54.46 mS cm -1 . The single fuel cell tests with QPV/PDD 0.5 membrane yield the maximum power density and current density of 8.6 mW cm -2 and 47.6 mA cm -2 at 57 °C. This study demonstrates that PVA-based AEMs have the potential for alkaline direct ethanol fuel cells (ADEFCs) application. }, pages = {435--443} doi = {10.14710/ijred.2021.33168}, url = {https://ejournal.undip.ac.id/index.php/ijred/article/view/33168} }
