ABSTRACT:
A flowable substance is applied to at least one predetermined area of a major surface of a plate-shaped fuel cell component by directing at least one stream of the flowable substance toward a predetermined zone that is situated in a plane along which the major surface of the component extends, facing the stream. The size of the predetermined zone is smaller than that of the predetermined area, and relative movement along the plane is effected between the component and the predetermined zone in such a manner that at least the entire predetermined area of the major surface gradually advances through the predetermined zone in a predetermined advancement direction and path. The stream is controlled in such a manner that it is in existence only while the zone is completely within the predetermined area, and until the zone has coincided with all of the predetermined area.
