Author:Luo, H; Vaivars, G; Modibedi, Remegia M; Mathe, Mahlanyane KDate:Jul 2009The low-cost cross-linked Polyetheretherketone (PEEK) proton exchange membranes were prepared via the simple route. The membranes exhibited similar electrochemical properties as compared with commercial Nafion. The membranes were highly proton ...Read more
Author:Lou, H; Vaivars, G; Mathe, Mahlanyane KDate:Oct 2009The low cost proton exchange membrane was prepared by cross-linking water soluble sulfonated-sulfinated poly(oxa-p-phenylene-3,3-phthalido-p-phenylene-oxa-p-phenylene-oxyphenylene) (SsPEEK-WC). The prepared cross-linked membrane became insoluble ...Read more
Author:Luo, H; Vaivars, G; Mathe, Mahlanyane KDate:Apr 2012The proton exchange membrane based on polyetheretherketone was prepared via two steps of cross-linking. The properties of the double cross-linked membrane (water uptake, proton conductivity, methanol permeability and thermal stability) have ...Read more
Author:Luo, H; Vaivars, G; Mathe, Mahlanyane K; Zheng, HaitaoDate:Aug 2009The proton exchange membrane is a key component of polymer electrolyte membrane fuel cell (PEMFC). It plays an important role, conducts protons and separates the fuel from oxidant in PEMFC. DuPont’s Nafion is a perfluorinated sulfonic acid ...Read more
Author:Sigwadi, R; Dhlamini, MS; Mokrani, T; Nemavhola, F; Nonjola, Patrick NT; Msomi, PFDate:Aug 2019Zirconium phosphates (ZrP) were incorporated into Nafion® 117 membrane by impregnating method to obtain a reduced methanol permeation and improved proton conductivity for fuel cell application. The mechanical properties and water uptake of ...Read more
