An efficient proton conducting electrolyte membrane for high temperature fuel cell in aqueous-free medium

摘要: Abstract A novel composite membrane, derived from a simple combination of phosphate based alkylimidazolium ionic liquid used as an anhydrous proton conductor in sulfonated poly (ether ether ketone) polymer matrix, was first proposed and characterized. Observed thermal, mechanical chemical stabilities doped membranes were finest to use fuel cell applications. The effective conductivity with respect various compositions studied function different temperatures. Under environment the found have comparatively good range 1.25–3.16 mS cm–1 at 145 °C measured by impedance analyzer. Fuel performance SPEEK/50% IL membrane gave maximum power density 203 mW/cm2 145 °C. This study foresees that new could be promising water-free transport for cells.
