摘要： A method of analyzing a functional layer of an electrochemical cell or an electrochemical sensor application includes conveying a predefined amount of test gas to a first surface of the functional layer, and quantitatively determining an amount of test gas that has passed through the functional layer using a detection unit located on a second surface of the functional layer, which second surface is opposite the first surface of the functional layer, wherein the test gas conveyed to the first surface of the functional layer is provided in a test gas chamber arranged on the first surface of the functional layer, characterized in that the test gas chamber is open towards the first surface of the functional layer and has an opening which has a defined length in the longitudinal direction (X) of the functional layer and a variably adjustable width in the transverse direction (Z).

摘要： The present invention concerns a method for preparing a catalyst coated membrane including the steps of: coating a substrate with a first catalyst dispersion thereby obtaining a first catalyst dispersion coated substrate, providing a second side of a membrane with a support film, coating a first side of the membrane with a second catalyst dispersion, thereby obtaining a second catalyst dispersion coated first side of the membrane, drying the first catalyst dispersion thereby obtaining a first catalyst coated substrate or drying the second catalyst dispersion coated first side of the membrane thereby obtaining a second catalyst coated first side of the membrane, laminating the first catalyst coated substrate to the second catalyst dispersion coated first side of the membrane or laminating the first catalyst dispersion coated substrate to the second catalyst coated first side of the membrane so that the first catalyst and the second catalyst superimpose, thereby forming a laminate including a membrane comprising a first catalyst layer, drying the laminate, removing the support film from the second side of the membrane, coating a third catalyst dispersion on the second side of the membrane, drying the third catalyst dispersion, thereby obtaining a second catalyst layer on the membrane, and removing the substrate from the first catalyst coated substrate.
