Investigation Of Hydrogen Production By Using Composite Membrane (Nafion/Zro2)-Based Solid Polymer Electrolyte Water Electrolyser

In the present study, Composite materials based on perfluorinated cation-exchange membrane incorporating particles of Zirconium and Nafion is synthesized .With this membrane the performance of the electrolysis cell improved considerably at room temperature and atmospheric pressure. In addition, by using catalysts and membranes, the performance of this Composite membrane is studied by varying voltage range with respect to hydrogen yield and at current density 0.1, 0.2, 0.3, 0.4, and 0.5(A cm -2 ), With a Nafion 115 membrane as a reference electrolyte. Experiments have shown that 99.9% purity of hydrogen Gas is evolved The physicochemical properties of the composite membranes such as thermogravimetric analyzer (TGA), Scanning Electron Microscope (SEM), XRD (X-ray powder diffraction), Fourier transform infrared spectroscopyand and Ion Exchange Capacity is determined. The fabricated composite membranes have shown the significant improvement of all tested properties compared to that of pure Nafion membrane.
