| Summary: | 碩士 === 國立高雄應用科技大學 === 機械與精密工程研究所 === 97 === The method of fabrication DMFC electrode media on this research is using different combined solvent PTFE and Nafion, one to three mass ratio and mixed with XC-72 produce carbon nano ink. Spray and clad cover the carbon cloth with 50 μm film thickness. Apply Magnetron Sputter deposition media clad on carbon cloth shell. We also proceed other progress: emersion period as a operation parameter clad different mass quantity (0.072 mg/cm2, 0.144 mg/cm2, 0.216mg/cm2) Pt media to a electric chemical analysis, we can find by increasing media mass content can't strength the adsorption the carbon monoxide stripping on electrode surface. We also made (Pt50Ni50/C, Pt60Ni40/C, Pt70Ni30/C) Pt-Ni twin element electrode media to compare with mono element electrode media. Besides that, by using FE-SEM observe media porosity structure, EDS observe media element and its mapping spectrum. By using XRD analysis, Pt crystal structure is found to be Face-centered cubic (FCC), and the smallest media crystal grain size is calculate to be 4.9nm.
