PROTON CONDUCTOR, PROCESS FOR ITS PRODUCTION AND ELECTROCHEMICAL DEVICES

Title:

PROTON CONDUCTOR, PROCESS FOR ITS PRODUCTION AND ELECTROCHEMICAL DEVICES

Document Type and Number:

WIPO Patent Application WO/2003/034445

Kind Code:

A1

Abstract:

A novel proton conductor which is usable in dry atmosphere or in a relatively wide temperature range including room temperatures and is remarkably improved in proton conductivity&semi a process for the production thereof&semi and electrochemical devices. Specifically, a proton conductor made of a fullerene having a proton−liberating functional group bonded thereto through an at least three−membered ring structure&semi electrochemical devices made by using the same&semi and a process for the production of the above proton conductor which comprises preparing a fullerene derivative to which a functional group having an ester group is bonded through an at least three−membered ring structure, hydrolyzing this derivative with an alkali hydroxide, and subjecting the resulting hydrolyzate to ion exchange to form a proton−liberating group.
