Abstract

Metallized cation-exchange membrane The present invention relates to a membrane/electrode composite comprising a membrane comprising a polymeric cation exchanger containing carboxylic acid, phosphonic acid or sulfonic acid groups, which cation exchanger is soluble in a solvent, where on at least one side of the membrane there are applied finely divided metals which catalyze the formation of water from H.sub.2 and O.sub.2. The part of the membrane covered with metal is porous, but contains no closed pores, and the metal can also be present in the pores.
