Abstract (en)

[origin: WO0171334A1] The present invention relates to a method for producing a gas diffusion membrane. A layer (4) that is applied to a carrier material (3) is thinned by means of the effects of laser radiation (6). The invention also relates to gas diffusion membranes and gas sensors containing such gas diffusion membranes, whereby said membranes and sensors are produced according to the inventive method.
