Characterization of Electrolyte Polyester Membranes for Application in PEM Fuel Cells
(234–240)Macromolecular Symposia 299-300 #1 (2011)
Fiuza  et al of the Universidade Federal da Bahia - UFBA,, Brazil  prepared membranes by two different methods: Firstly, the MEB series were prepared by the addition of sodium dodecyl sulphate (SDS) to the resin obtained from the polymerization of terephthalic and adipic acid with glycerol. Secondly, the MP series were prepared from the polymerization of maleic acid and glycerol, phosphotungstic acid (PWA) was afterwards added to this material. The composites were processed in a reactor and shaped by hot pressing, yielding homogeneous and flexible slabs with an excellent surface finish.. The developed materials showed good properties as electrolyte
