PROTON CONDUCTOR, PROCESS FOR PRODUCING THE SAME, AND ELECTROCHEMICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2002/058079
Kind Code:
A1
Abstract:
A proton conductor which comprises silicon oxide, a Brfnsted acid, and a carbonaceous material derivative obtained by introducing proton (H?+¿)-releasing groups onto carbon atoms contained in a carbonaceous material which consists mainly of carbon. This proton conductor is produced through the steps of producing a compound comprising silicon oxide and a Brfnsted acid as major components by the sol-gel method and mixing the compound with a carbonaceous material derivative obtained by introducing proton (H?+¿)-releasing groups onto carbon atoms contained in a carbonaceous material which consists mainly of carbon.
