However, its major drawbacks include low proton conductivity, poor mechanical stability, and susceptibility to degradation under harsh conditions. To overcome these limitations, researchers have attempted to modify Nafion membrane using various approaches, including chemical modification, physical modification, and hybrid modification. This preliminary study aims to investigate the modification of Nafion membrane using different approaches and evaluate its potential as a proton exchange membrane.Objectives:The main objectives of this study are as follows:1. To modify Nafion membrane using chemical, physical, and hybrid approaches.2. To characterize the modified Nafion membranes using various techniques such as Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and thermogravimetric analysis (TGA).3. To evaluate the proton conductivity, water uptake, and mechanical stability of the modified Nafion membranes.4. To assess the performance of the modified Nafion membranes as proton exchange membranes in a single-cell fuel cell.Methodology:The following methodology will be adopted to achieve the objectives of the study:1. Preparation of Nafion membrane: Nafion membrane will be prepared using the solution-casting method.精品文档---下载后可任意编辑2. Chemical modification of Nafion membrane: Nafion membrane will be modified using chemical agents such as sulfur...
