The invention relates to a method for producing a catalyst coated membrane (19) for a fuel cell (10), wherein the catalyst coated membrane (19) has a membrane (11) and a catalyst layer (12, 13) of a catalytic material arranged on at least one of its flat sides, as well as a nonrectangular active area (20), which is restricted in one direction by two outer sides (30) opposite one another. The method comprises a continuous application of the catalytic material to a membrane material (33) while creating a constant coating width (B) such that an area (35) coated with the catalytic material corresponds to at least the active area (20). A provision is that the membrane material (33) be coated with the catalytic material such that a coating direction (D) has an angle with respect to the opposite outer sides (30) of the active area (20) that is not equal to 90° and not equal to 0°.
