Article Synopsis
  • Researchers developed a new type of block copolymer electrolyte combining a hydrophilic perfluorinated segment (poly(perfluoropropyl sulfonimide)) and a hydrophobic hydrocarbon segment (poly(ether ether sulfone)).
  • The sulfonimide group in the electrolyte exhibits superacidity with a low equivalent weight, resulting in a high proton conductivity of 1.2 × 10 S/cm in dry conditions at 25 °C.
  • At 20% relative humidity, the block copolymer achieved a proton conductivity of 1.7 × 10 S/cm, outperforming the well-known Nafion 112 by a factor of three.
