Abstract
A compound membrane for use in electrochemical devices is disclosed. The compound membrane has of proton-conducting polymer cast in a porous media having dispersed therein at least one active ingredients. It supplies considerably improved performance data in comparison to known membranes. The compound membrane electrode can be produced by treating proton-conducting polymers with acetone to obtain polymer pulp, then sulfonating the polymer pulp, combining one or more active ingredients with the polymer pulp and casting the polymer pulp to obtain the membrane.
