abstract = "We synthesized novel composite polymer electrolyte membranes of [EMIm](FH)nF (n = 1.3 and 2.3) ionic liquids and measured their physical and electrochemical properties. The ionic conductivities of composite membrane (P(VdF-co-HFP):s-DFBP-HFDP:[EMIm](FH)2.3F = 1:0.3:1.75 in weight ratio) were up to 11.3 and 34.7 mS cm-1 at 25 and 130°C, respectively. We also studied the fuel cell performance using these composite membranes at intermediate temperature without humidification. The OCV observed for the cell using [EMIm](FH)2.3F composite electrolyte was ∼1.0 V at 130°C and stable during the measurement conducted for over 5 h. The maximum power density of 14.8 mW cm-2 was observed at 37.2 mA cm -2 at 120°C. From the high thermal stability and high ionic conductivity, the fluorohydrogenate ionic liquid composite membranes seem to be promising candidate electrolytes for unhumidified PEMFCs at intermediate temperature. copyright The Electrochemical Society.",
