The invention relates to manufacturing method for components of a fuel cell stack from a mixture of plastic and at least one electrically conductive filler by means of a double belt press. The manufacturing method according to the invention is characterized in that an uncured or incompletely cured strip-shaped blank comprising the mixture is fed into an isochoric double belt press having individual segments, wherein each of the individual segments has a shaping structure for shaping the blank into the component as the blank passes through the double belt press, wherein the individual segments on the two belts of the double belt press position themselves relative to one another during the pressing process by means of corresponding locking elements. The invention further relates to a manufacturing method for bipolar plates and/or interface plates, the halves of which are manufactured according to the above method and are bonded to one another in an isobaric double belt press.
Manufacturing method for components of a fuel cell stack from a mixture, which at least comprises one plastic and at least one electrically conductive filler by means of a double belt press, wherein an uncured or incompletely cured strip-shaped blank from the mixture is fed into an isochoric double belt press having individual segments, wherein each of the individual segments has a shaping structure for shaping the blank into the component as the blank passes through the double belt press, wherein the individual segments on the two belts of the double belt press position themselves relative to one another by means of corresponding locking elements during the pressing process, which allows to map the shaping structures in the blank during the pressing process in a precise position, and at least one individual segment (4) is used, which comprises a shaping structure which differs from the shaping structures of the other individual segments.
