Abstract
The invention relates to a proton-conducting polymer membrane and to a method for the production thereof. Starting from a catalyst layer, which is homogeneously deposited on the polymer membrane (), the catalyst layer is subdivided into a number of catalyst segments () by microstructuring so that adjacent fuel cell units of a planar fuel cell arrangement can be realized in the smallest possible space.
