摘要註:	本研究利用季銨化反應(Quaternization reactions)，再使用特定鹽類或離子交換樹脂(Ion exchange resin)進行離子交換(Ion exchange)，合成製備具親水性質之離子液體包括[EMIM][Cl]，[EMIM][Br]，[BMIM][Cl]，具疏水性質之離子液體包括[EMIM][PF6]，[BMIM][PF6]，以及介於親水/疏水性質之離子液體包括[EMIM][BF4]，[BMIM][BF4]，並以1H-NMR，FT-IR，TGA和Ion Chromatography檢測各種離子液體之純度及特性。結果顯示，本實驗室合成製備之離子液體，產率約為55% ~ 95%，而純度均高於99%。將離子液體摻雜於本實驗室自行合成之磺酸化聚苯乙烯(PSS)中，配製不同的磺酸根/離子液體莫耳數比例之溶液，以溶液鑄膜(Solution casting)方式，製備質子交換複合膜，並以溶劑膠合(Solvent gluing)法製作膜電極組(MEA, membrane electrode assembly)，進行燃料電池組效能測試。結果顯示，相較於傳統熱壓法製備MEA，溶劑膠合法製備之MEA，在燃料電池組中的開環電位(Open circuit potential)由0.62V提升至0.95V。各種不同PSS/離子液體組合及莫耳數比例製備為1cmx1cm之MEA，經由燃料電池組I-E曲線量測，開環電位約在0.9842V至0.4655V之間，最大功率密度(Power density)則在13 mW/cm2至237.09mW/cm2之間，而相對應最大電流密度(Current density)約在3.3mA/cm2至555.9mA/cm2之間。以35.6 mol% PSS與[BMIM][BF4]混摻製成5cmx5cm之MEA，測試結果顯示，最大功率密度可達237.09mW/cm2，相較於商用以Nafion薄膜製備之MEA(最大功率密度約為208.8mW/cm2)，PSS/[BMIM][BF4]複合膜以膠合法製備之MEA，具有與Nafion相當的效能表現。 In this study, ionic liquids were synthesized utilizing quaternization reaction of imidazoles, followed by ion-exchanging using specific salts or ion-exchange resins. Purifications were performed either by extraction, salt-out effect, filtration and evaporation for liquid ionic liquids or by evaporation, dissolving and recrystallization for solid ionic liquids. The successfully synthesized ionic liquids were of [EMIM][Cl],[EMIM][Br],[BMIM][Cl],[EMIM][PF6], [BMIM][PF6],[EMIM][BF4], [BMIM][BF4].The natures of these synthesized ionic liquids were characterized using 1H-NMR, FT-IR, TGA and ion chromatography. The recovery yields for the synthesized ionic liquids were in the range of 55% to 95%. The purities of these ionic liquids were estimated over 99%. The details of synthesizing procedures, purifications and haracterizations were explored. The PSS/IL composite membranes were prepared by solution casting of PSS/ILs solutions in various mole ratio of sulfonated group to ionic liquid. Membrane electrode assemblys (MEAs) were manufactured using the solvent gluing method. The polarization curves (I-E curves) of fuel cells based on various PSS/IL composite membrane MEA were measured using a fuel cell test station. The results showed that open circuit voltages (OCVs) of fuel cells utilizing MEA prepared by solvent gluing method were enhanced to 0.95V, compared to that (0.62V) of MEA prepared by hot-pressing method. The electrode areas of MEA prepared with various ratio mole ratio of sulfonate group to ionic liquid were mainly 1 cm x 1 cm. OCVs ranged from 0.984 V to 0.4655 V were observed. Maximum power density varies from 13 mW/cm2 to 237.09 mW/cm2, and relative maximum current density ranged from 3.3 mA/cm2 to 555.9 mA/cm2. MEA based on 35.6mol%PSS/[BMIM][BF4] composite membrane showed the greatest performance result. Electrode area of 5 cm x 5 cm of MEA using 35.6mol%PSS/[BMIM][BF4] composite membrane was also prepared. It was found that this MEA possessed maximum power density of 237.09 mW/cm2, compared to the commercial Nafion-based MEA which showed maximum power density of 208.8 Mw/cm2. The results implied that PSS/[BMIM][BF4] composite membrane-based MEA prepared using solvent gluing method possessed performance ability equivalent to that of commercial Nafion-based MEA. That is, PSS/[BMIM][BF4] composite membrane-based MEA can be competitive for utilizing in fuel cell applications.
