Covalent-ionically cross-linked polyetheretherketone proton exchange membrane for direct methanol fuel cell

Author: Luo, H ; Vaivars, G ; Mathe, Mahlanyane K Date: Aug 2010 In this paper, the proton exchange membrane prepared by covalent-ionically crosslinking water soluble sulfonated-sulfinated poly(oxa-p-phenylene-3,3-phthalido-pphenylene- oxa-p-phenylene-oxy-phenylene) (SsPEEK-WC) is reported. Compared with ... Read more
Covalently cross-linked polyetheretherketone proton exchange membrane for DMFC

Author: Luo, H ; Vaivars, G ; Modibedi, Remegia M ; Mathe, Mahlanyane K Date: May 2009 The proton exchange membrane was prepared by covalent cross-linking sulfonated-sulfinated polyetheretherketone. The cross-linked membrane showed high proton conductivity (0.04 S/cm) with suitable water uptake, low methanol permeability (2.21 ... Read more
Cross-linked PEEK-WC proton exchange membrane for fuel cell

Author: Lou, H ; Vaivars, G ; Mathe, Mahlanyane K Date: Oct 2009 The 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
Double cross-linked polyetheretherketone proton exchange membrane for fuel cell

Author: Luo, H ; Vaivars, G ; Mathe, Mahlanyane K Date: Apr 2012 The 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
