Blending polyvinyl alcohol (PVA) -Carboxy methyl cellulose (CMC) - Acrylamide (AA) membranes are prepared and crosslinked using succinic acid and investigated it as a polymer electrolyte membrane (PEM) in direct methanol fuel cell (DMFC). The membranes were prepared through the solution casting technique. The effect of different blend addition on physicochemical properties was studied. Scanning el...
