These studies have been focused on the development of hydrocarbon-based (HC) polymer membranes as alternative electrolyte membranes to solve shortcomings of perfluorinated polymers such as high cost, high gas permeability and low chemical stability. Gadolinium-doped cerium oxide nanoparticles is introduced with sulfonated poly(ether ether ketone) (SPEEK) composite membrane. Membrane properties including swelling behaviors, ion exchange capacity, proton conductivity and chemical stability are carefully investigated comparing with the cerium oxide nanoparticle/SPEEK composite membrane. Particularly, degree of dispersion of composite membranes strongly affects the membrane properties, therefore, we identified property differences with different content of nanoparticles. |
