Abstract (en)
[origin: WO2021185404A1] Provision is made for a method for testing a bipolar plate of an electrochemical cell, in particular of a fuel cell, in which an image (12) of a surface of a bipolar plate (14) is created, the image (12) is investigated for possible defects (28) by an automated image processing-assisted evaluation system, and in the event of the evaluation system identifying an investigated bipolar plate (14) as a potentially defective suspect plate, a detailed test (22) is performed on a region of the suspect plate identified as potentially defective. By virtue of the evaluation methods applied in the automated evaluation system during the image processing of the image (12), it is possible to increase the test quality when testing a bipolar plate of an electrochemical cell, such as a fuel cell, without significant additional outlay, thereby allowing an inexpensive and reliable test.
