Abstract:
Disclosed are: an ionomer dispersion having high dispersion stability while also containing high content of ionomer solids, thus optimizing the ionomer morphology in a polymer electrolyte membrane to allow both the ion conductivity and durability of the polymer electrolyte membrane to be improved; a method for producing the ionomer dispersion; and a polymer electrolyte membrane produced using the method.
