本研究開發共價鍵結磺酸根高分子材料並應用於燃料電池的膜電極組中，其中包含磷酸燃料電池和質子交換膜燃料電池，主要目的皆為提升燃料電池之膜電極組的質子傳導能力，達到電池效能更進一步的目標。
在磷酸燃料電池研究的部分，藉由Diazonium反應，將磺酸根以共價鍵結的方式，接枝至聚苯並咪唑 (Polybenzimidazole, PBI) 膜上，使質子交換膜的質子傳導度更進一步的提升。在改質完PBI膜後，透過傅立葉紅外線光譜儀(FTIR)進行樣品檢測，確認改質後質子交換膜的鍵結，依此判斷改質實驗是否成功，並在後續的單電池測試中，得到高於商用PBI效率的516 mW/cm2。
近幾年許多國家也開始限制含氟化合物相關商品的出口，而質子交換膜燃料電池會使用到含氟的液態高分子電解質Liquid Nafion，因此本研究為開發出不含氟的磺化聚苯胺高分子來代替原本作為離子聚合物(Ionomer)的Liquid Nafion，並且以自製的Ionomer提高膜電極組的質子傳導度，透過增加三相區(觸媒-燃料-電解質)中的磺酸根密度，在使用自製磺化高分子的單電池測試中，成功測得比商用質子交換膜燃料電池還優秀的電池效率。

In order to improve the proton conductivity of the membrane electrode assembly (MEA), we develop the polymeric materials functionalized with sulfonic groups in this research. The application of the polymeric materials are for membrane electrode assemblies of the fuel cell, including Phosphoric Acid Fuel Cell (PAFC) and Proton Exchange Membrane Fuel Cell (PEMFC). By increasing the proton conductivity of the membrane electrode assemblies, the power density of the fuel cell can be improved.
The part of the phosphoric acid fuel cell research, the sulfonic groups were covalently bonded to the polybenzimidazole (PBI) membrane by the Diazonium reaction, which further improved the proton conductivity of the proton exchange membrane. After the modification of the PBI membrane, the samples were tested by Fourier transform infrared spectrometer (FTIR) to confirm the bonding of the modified proton exchange membrane. Based on this, it was judged whether the modification experiment was successful. In the single fuel cell test, the maximum power density with modified PBI membrane is 516 mW/cm2 which is higher than the commercial phosphoric acid fuel cell.
In recent years, many countries have restricted the export about fluorine-containing compounds. However, the Liquid Nafion as liquid polymeric electrolyte (also called Ionomer) plays an important role in the proton exchange membrane fuel cell. The experiment develops the sulfonated polyaniline (SPANI) which is not only fluorine-free to replace Liquid Nafion as ionomer originally, but also applied in MEA of the PEMFC to improve the proton conductivity. The higher the sulfonated group density in the three phase zone (Catalyst-Fuel-Electrolyte), the better the fuel cell power density. Successfully, the single fuel cell test with homemade sulfonated polymer got the better performance than the commercial proton exchange membrane fuel cell.
