Abstract
The invention relates to a method for producing a multi-layer, in particular five-or six-layer, membrane-electrode arrangement (1) comprising a polymer membrane (2), which arrangement has, in order to form an anode (3) and a cathode (4), a catalyst layer (5, 6) and a gas diffusion layer (7, 8) on both sides. According to the invention, the anode-side catalyst layer (5) is applied to the anode-side gas diffusion layer (7) in a wet-chemical coating method, is initially dried, and is joined to the polymer membrane (2) prior to complete drying.
