摘　　要：以甲醇为溶剂制备氢氧化钾/甲醇溶液作铝阳极电解液、以水为溶剂制备氢氧化钾溶液为空气阴极电解液,制得一种双电解质铝空气微流体燃料电池。1 000μL/min下,阳极电解液含水量20%时电池短路电流密度为270 mA/cm^2,最大功率密度90 mW/cm^2,铝自腐蚀率仅为在氢氧化钾水溶液中的10.5%。总的来说,含氢氧化钾/甲醇溶液的双电解质铝空气微流体燃料电池应用到小型电子设备中是具有吸引力的。A dual electrolyte aluminum air microfluidic fuel cell was prepared by preparing potassium hydroxide/methanol anolyte using methanol as solvent and potassium hydroxide catholyte using water as solvent.At 1 000 μL/min,the cell short-circuit current density is 270 mA/cm^2 with 20% water content of anodolyte and the maximum power density is 90 mW/cm^2 with the aluminum self-corrosion rate is only 10.5% of that in the potassium hydroxide aqueous solution.In general,the application of dual electrolyte aluminum air microfluidic fuel cells containing potassium hydroxide/methanol solution into small electronic devices is attractive.
