Method for treating bipolar plate of fuel cell, involves testing component non-destructively by ultrasound beam, and injecting ultrasound beam into component through fine beam linking using beam of cleaning liquid

The method involves cleaning a component (3) by a cleaning liquid (7). The component is non-destructively tested by an ultrasound beam, where the ultrasound beam is injected into the component through a fine beam linkage using a beam of the cleaning liquid. The component is partially immersed into a bath (9) of the cleaning fluid. The ultrasound is injected via the bath of the cleaning fluid. The cleaning liquid includes one of volatile, waterless, non-corrosive and inert properties. The ultrasound beam is coupled by a coupling medium. An independent claim is also included for a manufacturing station for non-destructively testing and cleaning a bipolar plate of a fuel cell, comprising a fluid guide. Die Erfindung betrifft ein Verfahren zur Behandlung eines Bauteils. Um eine effizientere Behandlung des Bauteils zu erzielen, wird das Verfahren mit: Reinigen des Bauteils (3) mittels einer Reinigungsflüssigkeit (7) und zerstörungsfreiem Prüfen des Bauteils (3) mittels Ultraschall und dazu Einkoppeln des Ultraschalls in das Bauteil (3) mittels der Reinigungsflüssigkeit (7) durchgeführt.
