Preparation of KOH-doped PVA/PSSA solid polymer electrolyte for DMFC: the influence of TiO 2 and PVP on performance of membranes
The development of low cost alkaline anion solid exchange membranes requires high ionic conductivity, low liquid uptake, strong mechanical properties and chemical stability. PVA/PSSA blends cross-linked with glutaraldehyde and decorated with titanium dioxide nanoparticles introduce advantages relati...

| Sumario: | The development of low cost alkaline anion solid exchange membranes requires high ionic conductivity, low liquid uptake, strong mechanical properties and chemical stability. PVA/PSSA blends cross-linked with glutaraldehyde and decorated with titanium dioxide nanoparticles introduce advantages relative to the pristine membrane of PVA and PVA/PVP membranes due to their improved electrical response and low methanol uptake/ swelling ratio allowing their use in alkaline direct methanol fuel cells |
