    Abstract: 81787236 ABSTRACT Provided is a polymer electrolyte composition, and a polymer electrolyte membrane, a membrane electrode complex and a solid polymer-type fuel cell containing the composition. The composition comprises an ionic-group-containing polymer and a nitrogen-containing additive having a structure of (C1) or (C2). The additive has excellent chemical stability to tolerate a strongly acidic atmosphere, solubility in various general-purpose organic solvents, superior processability, and can be mixed with an ionic-group-containing polymer. The additive resists elution under a strongly acidic atmosphere during the operation of a fuel cell, can prevent the occurrence of phase separation during the formation of a film, and can prevent formation of an island-in-sea-like phase-separated structure or occurrence of bleeding out during the formation of a film. The polymer electrolyte composition can achieve excellent proton conductivity under slightly humidified conditions, excellent mechanical strength and excellent physical durability.
