In solid polymer electrolyte having high-durability, comprising a polymer electrolyte material having a hydrocarbon part, a chelate group and an electrolyte group are introduced into the polymer electrolyte material. The chelate group contains a phosphonic acid group, nitrogen, both of nitrogen and a phosphonic acid group (one or more selected from the group consisting of alkylamino monophosphonic acid groups, alkylamino diphosphonic acid groups, dialkylamino monophosphonic acid groups, alkylalkylene diamine triphosphonic acid groups, and alkylimino phosphonic acid groups) or, both of nitrogen and a carboxylic acid group (one or more selected from the group consisting of alkylamino monocarboxylic acid groups, alkylamino dicarboxylic acid groups, dialkylamino monocarboxylic acid groups, alkylalkylene diamine tricarboxylic acid groups, and alkylimino carboxylic acid groups).
A solid polymer electrolyte, comprising a polymer having electrolyte groups selected from the group consisting of sulfonic acid groups, carboxylic acid groups, and sulfone imide groups, and a chelate group,
A solid polymer electrolyte comprising chelate groups and a polymer having electrolyte groups, wherein at least a portion of the polymer is a hydrocarbon, and the chelate group comprises at least one acid group selected from the group consisting of alkylamino monophosphonic acid groups, alkylamino diphosphonic acid groups, dialkylamino monophosphonic acid groups, alkylalkylene diamine triphosphonic acid groups, and alkylimino phosphonic acid groups.
A solid polymer electrolyte comprising chelate groups and a polymer having electrolyte groups, wherein at least a portion of the polymer is a hydrocarbon, and the chelate group comprises at least one acid group selected from the group consisting of alkylamino monocarboxylic acid groups, alkylamino dicarboxylic acid groups, dialkylamino monocarboxylic acid groups, alkylalkylene diamine tricarboxylic acid groups, and alkylimino carboxylic acid groups.
A solid polymer electrolyte comprising chelate groups and a polymer having electrolyte groups, wherein at least a portion of the polymer is a hydrocarbon, and the solid polymer electrolyte has a proton conductivity at 25° C. which is more than or equal to 10−2 S/cm.
