Title:
PROTON-CONDUCTING POLYMER MEMBRANE AND METHOD FOR THE PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO2003100882
Kind Code:
A3
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 (3), the catalyst layer is subdivided into a number of catalyst segments (1a, 1b) by microstructuring so that adjacent fuel cell units of a planar fuel cell arrangement can be realized in the smallest possible space.
