Process for producing a polar plate semi-finished product and a polar plate, as well as a polar plate

摘要

The invention relates to a method for producing an endless semi-finished polar plate (80, 88) for polar plates (90) for electrochemical cells, in particular fuel cells, in which, in a first step of the method, a first endless polar plate film (80, 82) is made available from an electrically conductive composite polymer (98), in a second step of the method, a target thickness of the endless polar plate film (80, 84/86) is set by a rolling process of the endless polar plate film (80, 82), and in a third step of the method, the endless polar plate film (80, 84/86) is given its final shape by a shaping process and an endless semi-finished polar plate (80, 88) is obtained.
