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.
