Title:
METAL ION-BRIDGED PHOSPHONATED FULLERENE AND METHOD FOR MANUFACTURING THE SAME, AND PROTON CONDUCTIVE FILM CONTAINING THE SAME
Document Type and Number:
Japanese Patent JP2009046571
Kind Code:
A
Abstract:
To provide chemically modified fullerene which is useful for manufacturing a proton conductive film for a fuel cell, and has a phosphonic acid group or a sulfonic acid group, and is made insoluble.
This invention relates to a metal ion-bridged phosphonated fullerene, wherein a phosphonic acid group of the chemically modified fullerene having substantially no organic compound bonded, is bridged with cerium ion or manganese ion. The fullerene contains the 1 to 12 phosphonic acid groups in a form of a partial structure H-C-C-PO(OH)2.
