Title:
METHOD FOR FULLERENE DERIVATIVE AND THE FULLERENE DERIVATIVE, PROTON CONDUCTOR AND ELECTROCHEMICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2002/051782
Kind Code:
A1
Abstract:
A method for preparing a fullerene derivative, wherein a fullerene derivative having a group capable of liberating a proton introduced to a carbon atom constituting the fullerene molecule is formed by using a halogenated fullerene formed by halogenating a fullerene molecule as a precursor; a method for preparing a polymerized fullerene derivative, wherein a plurality of fullerene molecules are reacted with an aromatic compound molecule to form a polymer comprising a plurality of fullerene molecules which are bound to one another via the aromatic group of the aromatic compound; a novel and useful proton conductor obtained by using the method; and an electrochemical device, such as a fuel cell, using the proton conductor. The above methods allow the efficient preparation of a fullerene having OH groups or SO¿3?H groups such as fullerenol suitable as a proton conductor. A fullerene derivative prepared by these production methods acts as a proton conductor. The electrochemical device is free from the restriction of atmosphere and thus can be miniaturized and simplified.
