Abstract

The present invention provides a fluoropolymer electrolyte material which has improved processability and which is easily produced. The electrolyte emulsion of the present invention comprises an aqueous medium and a fluoropolymer electrolyte dispersed in the aqueous medium. The fluoropolymer electrolyte has a monomer unit having an SOZ group (Z is an alkali metal, an alkaline-earth metal, hydrogen, or NRRRR, and R, R, R, and Reach are individually a C1-C3 alkyl group or hydrogen). The fluoropolymer electrolyte has an equivalent weight (EW) of 250 or more and 700 or less and a proton conductivity at 110° C. and relative humidity 50% RH of 0.10 S/cm or higher. The fluoropolymer electrolyte is a spherical particulate substance having an average particle size of 10 to 500 nm. The fluoropolymer electrolyte has a ratio (the number of SOF groups)/(the number of SOZ groups) of 0 to 0.01.
