Abstract (en)
[origin: WO0148854A2] The invention relates to a membrane electrode assembly for a fuel cell, in particular a PEM fuel cell and to a method for producing the same. According to said method, the expensive precious metal is distributed asymmetrically over the membrane according to the requirements of each area. The production method is characterised in that the electrodes are first coated with the membrane and not vice versa.
