ION-CONDUCTING PARTICLE AND MANUFACTURING METHOD THEREFOR, ION-CONDUCTING COMPOSITE, MEMBRANE ELECTRODE ASSEMBLY (MEA), AND ELECTROCHEMICAL DEVICE

摘要

PPROBLEM TO BE SOLVED: To provide an ion-conducting fine particles having ion dissociative groups and showing affinity to a fluorine-containing resin, and a method of manufacturing the same, and to provide an ion-conducting complex containing the ion-conducting fine particles, a membrane-electrode assembly (MEA) using the ion-conducting complex as electrolyte, and an electrochemical device, such as fuel cell. PSOLUTION: The method of manufacturing the ion-conducting fine particles 1 includes the steps of causing reactive molecules 13 to act on material fine particles 11, having ion dissociative groups 3 and a first reactive groups 12 on the surfaces of base material fine particles 2, the reactive molecules having second reactive groups 14 to be bound to the first reactive groups 12 only at one ends, and containing atom groups 5 having affinity to the fluorine-containing resin, at the main parts and/or the other ends; and introducing reformed groups 4 into the surfaces of the base material fine particles 2 with the reaction of the first reactive groups 12 with the second reactive groups 14, the reformed groups being bound only at one ends to the surfaces of the base material fine particles 2 and containing the atom groups 5 having affinity to the fluorine-containing resin, at the main parts and/or the other ends.
