BLEND POLYMER ELECTROLYTE, ELECTROLYTIC MEMBRANE BASED ON THE SAME, AND MEMBRANE/ELECTRODE CONJUGATE USING THE ELECTROLYTE

摘要

PROBLEM TO BE SOLVED: To provide a polyelectrolyte having high ionic conductivity at low humidities and suitable for a proton exchange membrane or the like in fuel cell, to provide an electrolytic membrane based on the polyelectrolyte, and to provide a membrane/electrode conjugate including the polyelectrolyte. SOLUTION: This blend polymer electrolyte is composed of a blend of an acidic group-bearing polymer with a water-absorbing compound.
