摘要
The invention relates to a cation- and/or proton-conducting membrane, to a process for producing it, and to its use. The membrane of the invention represents a novel class of solid, proton-conducting membranes. It is based on a porous and flexible ceramic membrane described in PCT/EP98/05939. The latter is modified so that it has ion-conducting properties. This membrane is subsequently treated with an ionic liquid. As a result of the use of the ionic liquid, the membrane of the invention has very good proton/cation conductivity even at temperatures above 100° C. The proton/cation-conducting ceramic membrane remains flexible and may be used without problems as a membrane in a fuel cell.
