Abstract
ABSTRACT Nation-silicon oxide (Si02)-phosphotungstic acid (PW A) composite membrane has been synthesized for medium temperature Proton Exchange Membrane Fuel Cell (PEMFC) application using sol-gel method. X-ray diffraction (XRD) was used to determine saturated absorption of PW A in the silica matrix. A transparent film was achieved at annealing temperature of 140°C over 10 hours duration. The film than was characterized by Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM) and Fourier Transform Infrared Spectroscopy (FTIR). The SEM and TEM results indicated homogenous structure of the Nation-Si02-PWA composite membrane with, Si02 and PWA particles size less then 10 nm. X-Ray Diffraction (XRD) result showed that the maximum loading of PWA in the Si02 matrix is in the ratio of PW NSi02 equal to 0.45 (wt.lwt.). The vibration absorption peak of Si-O-Si bond at 800 ern" and W-O-Wat 755 cm-I were observed thus indicated the inorganic compound was embedded in the Nation matrix and did not leach out after washing treatment using acid and base solutions.
