Structure and electrical properties of polymer electrolyte membrane for fuel cell application

Abstract

In this study to investigate the Polymer Electrolyte Membrane or Proton Exchange Membrane (PEM) that were synthesized by using acrilonitrile butadiene styrene (ABS). In order to enhance ability as a proton conductive polymer membrane as electrolyte, amorphous and crystalline silica ( 3 % and 5 %) were added to the initial mixture of ABS to inhibit relatively high proton conductivity. The structural and morphological characterization of samples was done by X-ray powder diffractometer, FTIR and scanning electron microscopy. Electrical properties were determined by LCR-meter (HIOKI 3522-50LCR HiTESTER). The structure analysis shows that the ABS amorphous phase with the unsmoth surface. The electrical conductivity of Polymer Electrolyte Membrane is 4,21 x10-3 S/cm of ABS with 5 % amorphous silica.
