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