摘要: 为优化改善燃料电池的整体性能,在自由电解质燃料电池中,考察了五种咪唑类离子液体用作燃料电池电解质时对燃料电池性能的影响。结果表明,以氢气为燃料时,在相同电流密度下,电路电压和输出功率从高到低依次为1-丁基-3-甲基咪唑四氟硼酸盐 > 1-丁基-3-甲基咪唑六氟磷酸盐 > 氢氧化钠溶液 >> 氯化-1-丁基-3-甲基咪唑 > 溴化-1-丁基-3-甲基咪唑 > 1-丁基-3-甲基咪唑硫酸氢盐;以甲烷为燃料时,相同电流密度下,电路电压和输出功率从高到低则依次为溴化-1-丁基-3-甲基咪唑 > 1-丁基-3-甲基咪唑硫酸氢盐 > 氯化-1-丁基-3-甲基咪唑 > 氢氧化钠溶液> 1-丁基-3-甲基咪唑四氟硼酸盐 > 1-丁基-3-甲基咪唑六氟磷酸盐。以[Bmim]BF4为氢气燃料电池电解质时,温度升高和离子液体中水含量增加,均会使燃料电池的性能减弱。
