摘要

本論文是將PBI薄膜進行改質，加入磺酸化的PBI和無機物Zr(HPO4)2，成為PBI/PBI-BS/Zr(HPO4)2摻合膜，觀察PBI-BS及Zr(HPO4)2對PBI膜之物理性質及燃料電池性能之影響。利用FTIR對PBI、PBI-BS進行結構鑑定，並將製備出的PBI/PBI-BS/Zr(HPO4)2摻合膜材進SEM (Scanning Electron Microscope)觀察膜材表面以及截面的結構、EDS (Energy Dispersive Spectrometer)分析膜材內元素成分、TGA (thermogravimetric analysis)檢測膜材的熱穩定性，並將膜材與觸媒層組成膜電極組(membrance electrode assembly, MEA)進行單電池測試。

In this thesis, polybenzimidazole (PBI) membrane was modified with sulfobutylated polybenzimidazole (PBI-BS) and zirconium phosphate (Zr(HPO4)2). The influences of Zr(HPO4)2 and PBI-BS on PBI PEMFC performance at 140~180℃ was investigated in this work. The chemical structures of PBI and PBI-BS were identified by FTIR spectrometer. The morphology of surface and cross section of the membrances was observed by SEM (Scanning Electron Microscope), and EDS (Energy Dispersive Spectrometer). TGA (thermogravimetric analysis) was used to carry out thermo properties of membranes. The membranes were fabricated with the catalyst layers to prepare MEA and carried out single cell tests.
