Anion exchange membrane based on alkali doped poly(2,5-benzimidazole) for fuel cell

Author: Luo, H ; Vaivars, G ; Agboola, B ; Mu, s ; Mathe, Mahlanyane K Date: Feb 2012 The properties of alkali doped poly(2,5-benzimidazole) membrane with different alkali doping level for fuel cell application is reported in this work. The alkali doping level played an important role for the ion conductivity of the membrane. ... Read more
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
