Sodium dodecyl sulfate/Pd composites has been synthesized and used to modify the surface of Nafion membrane. The modified Nafion has been characterized by Fourier transform infrared spectroscopy (FTIR) and field emission scanning electron spectroscopy (FE-SEM). The properties of the modified membranes, in terms of their conductivity and the performance of the membrane electrode assembly (MEA) in the...
Nafion is modified by incorporating poly(1-vinylimidazole)/Pd composites into the ion cluster channels of the membrane. The poly(1-vinylimidazole)/Pd-impregnated (PVI/Pd-impregnated) membranes is characterized by means of X-ray photoelectron spectroscopy (XPS), proton conductivity and methanol permeability measurements and compared with those of the untreated Nafion. The dependence of the membrane...
The surface of Nafion was modified by applying palladium nanoparticles as methanol barrier materials to decrease methanol crossover and improve the performance of fuel cells. The properties of the Pd-modified membrane, in terms of conductivity, methanol permeability, percentage of liquid uptake as well as the performance of its membrane electrode assembly (MEA) in the direct methanol fuel cell, were...
