Membranelektrodenanordnung für eine Brennstoffzelle, Verfahren zu deren Herstellung sowie Brennstoffzellensystem damit

摘要

The invention concerns a membrane-electrode assembly for a fuel cell, a method of preparing the membrane-electrode assembly, and a fuel cell system including the membrane-electrode assembly. The membrane-electrode assembly includes an anode and a cathode disposed opposite to each other, and a polymer electrolyte membrane interposed between the anode and the cathode. The polymer electrolyte membrane has a surface roughness on at least one side, and a metal layer is randomly formed on the at least one side of the membrane showing the mentioned surface roughness.
