| 摘 要： | 本文采用N-甲基咪唑为原料通过溴盐的中间步骤合成了1-乙基-3甲基咪唑磷酸二氢盐([Emim]H2PO4)离子液体。首先利用元素分析和核磁共振确定了其组成，并测量了该离子液体的粘度和电导性能，然后使用多孔的聚偏氟乙烯作为支撑制备了离子液体电解质复合膜，120 ℃时通过交流阻抗测得其电导率为2.7×10-2 S·cm-1。最后将该复合膜组装在单电池中测试了不同温度下的性能，常压下120 ℃时可获得0.85 mW·cm-2的功率密度，结果表明该复合膜的质子传导可以完全不依赖水，从而能够实现高温操作。

| Abstract: | With N-imidazole as staring material and [Emim]Br as intermediate, 1-ethyl-3-methylimidazol dihydrogen phosphate ([Emim]H_2PO_4) was synthesized and was soaked in the PVDF membrane as composite fuel cell electrolyte. The conductivity and viscosity of the ionic liquid was measured, and the composite membrane was characterized for conductivity as well. Fuel cell test was carried out at 120 ℃ and a maximum power density of conductor independent of water. |
