Anionic-exchange membrane development for application in alcohol alkaline fuel cells

Author: Nonjola, S Date: Sep 2010 Ammonium quaternized polymers such as poly (arylene ether sulfones) are being developed and studied as candidates of ionomeric materials for application in alkaline fuel cells, due to their low cost and promising electrochemical properties. ... Read more
Characterization of an anionic-exchange membranes for direct methanol alkaline fuel cells

Author: Abuin, GC ; Nonjola, Patrick NT ; Franceschini, EA ; Izraelevitch, FH ; Mathe, Mahlanyane K ; Corti, HR Date: Jun 2010 Ammonium quaternized polymers such as poly (arylene ether sulfones) are being developed and studied as candidates of ionomeric materials for application in alkaline fuel cells, due to their low cost and promising electrochemical properties. ...

Chemical modification and characterization of quaternized polysulfones.

Author: Nonjola, Patrick NT ; Mathe, Mahlanyane K ; Hietkamp, S Date: Dec 2008 Synthesis and characterization of anion-exchange membranes (AEMs) using polysulfones is described. The modification process of polysulfones involves two steps: Firstly, by introducing chloromethyl groups followed by quaternization reaction ... Read more
A high selectivity quaternized polysulfone membrane for alkaline direct methanol fuel cells

Author: Abuin, GC ; Franceschini, EA ; Nonjola, Patrick NT ; Mathe, Mahlanyane K ; Modibedi, Remegia M ; Corti, HR Date: 01 Apr 2015 Alkaline membranes based on quaternized poly(arylene ether sulfone) (QPAES) were characterized in relation to their water and methanol uptake, methanol permeability, electrical conductivity, and mechanical properties. The performance of QPAES ... Read more
