Abstract
A method for production and processing of a framed proton-conducting membrane for a fuel cell, comprises: providing of the proton-conducting membrane and a frame comprising at least two media ports inserting the membrane into a recess of the frame, processing of at least one surface of the frame such that a first region exists with an increased force of adhesion for a joining by means of gluing, and at least one second region exists with a lesser force of adhesion than the increased force of adhesion.
