Abstract

See full text

The present invention relates to a polymer electrolyte membrane for fuel cells, comprising a polymer matrix of at least one basic polymer and one or more doping agents, wherein particles containing ionogenic groups and having a mean particle diameter in the nanometer range are embedded in the polymer matrix and the particles containing ionogenic groups are distributed homogeneously in the polymer matrix in a concentration of less than 50% relative to the weight of the polymer matrix, as well as to the production and use of same, especially in high-temperature fuel cells.
