Title:
ION-CONDUCTING PARTICLE AND MANUFACTURING METHOD THEREFOR, ION-CONDUCTING COMPOSITE, MEMBRANE ELECTRODE ASSEMBLY (MEA), AND ELECTROCHEMICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/007702
Kind Code:
A1
Abstract:
Provided are: an ion-conducting particle that has an ionic dissociative group and exhibits affinity for a fluorine-containing resin; a method for manufacturing said ion-conducting particle; an ion-conducting composite containing the ion-conducting particle; a membrane electrode assembly (MEA) using said ion-conducting composite as an electrolyte; and an electrochemical device such as a fuel cell. The ion-conducting particle (1) is prepared by having a reactant molecule (13) act on a starting particle (11). The starting particle has a first reactive group (12) and an ionic dissociative group (3) on the surface of a base particle (2). The reactant molecule has, on only one end, a second reactive group (14) that can bond with the first reactive group (12), and contains on the body and/or other end a group of atoms (5) that exhibits affinity for a fluorine-containing resin. A reaction between the first reactive group (12) and the second reactive group (14) introduces a modifying group (4) onto the surface of the base particle (2), where only one end of the modifying group bonds to the surface of the base particle (2) and the body and/or other end of the modifying group contains a group of atoms (5) that exhibits affinity for a fluorine-containing resin.
