The invention relates to a catalytically active, permeable composite material, a method for producing said composite material, and the use of the composite material. The inventive composite material can be used for separating mixtures of materials. The fact that various catalytically active substances can be incorporated into the material in various ways makes it highly flexible in terms of possible applications with properties which can be adapted to the particular purpose of an application. The inventive composite material can be used as a catalytically active membrane electrode, for example. According to the invention, the material is obtained by solidifying a suspension on and in a porous, permeable support. The production of the material requires either a very short period of heat treatment at temperatures of around 400.degree. C. or treatment for a longer period at very mild temperatures of below 100.degree. C.

[ What is claimed is:] [1.]1. Catalytically active permeable flexible composite based on at least one perforated and permeable carrier, which contains on at least one side of the carrier and inside the carrier at least one inorganic component, which consists essentially of at least one compound of a metal, a metalloid or a composition metal and at least one element from group III to VII of the periodic system, which permeable flexible composite is obtained by application of a suspension, which contains said at least one inorganic component and a sol, on and inside at least one flexible, perforated and permeable carrier, and stabilizing the suspension by heating the suspension at least once either at a temperature of between 50 and 100.degree. C. for 10 minutes to 5 hours, or at a temperature of between 100 and 800.degree. C. for 1 second to 10 minutes,wherein said composite can be wound on or off a roll.
