ELECTROLYTE EMULSION AND PROCESS FOR PRODUCING SAME |
摘要 |
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 SO 3 Z group (Z is an alkali metal, an alkaline-earth metal, hydrogen, or NR 1 R 2 R 3 R 4 , and R 1 , R 2 , R 3 , and R 4 each 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 SO 2 F groups) / (the number of SO 3 Z groups) of 0 to 0.01. |
