Abstract: Described herein is a composite comprising a fluorinated polymer and nanoparticles of lithium fluoride. The lithium fluoride has an average BET surface area of at least 10 m2/g. The fluorinated polymer includes a fluorinated polymer backbone chain and a plurality of groups represented by formula –SO2X, in which each X is independently -NZH, -NZSO2(CF2)1-6SO2X', -NZ[SO2(CF2)dSO2NZ]1-10SO2(CF2)dSO2X', or -OZ, and Z is independently a hydrogen, an alkali-metal cation, or a quaternary ammonium cation, X' is independently –NZH or –OZ, and each d is independently 1 to 6. A polymer electrolyte membrane, an electrode, and a membrane electrode assembly including the composite are also provided.
