Description

Technical Field

[0001] This utility model relates to the field of fuel cell manufacturing and testing technology, and in particular to an automated testing device for testing the contact resistance of fuel cell bipolar plates. Background Technology

[0002] Bipolar plates are one of the core components of proton exchange membrane fuel cells, and their contact resistance directly affects the stack's output efficiency. Currently, most common contact resistance testing equipment on the market relies on manual placement of bipolar plates. The alignment deviation between the probe and the test point is >3mm, resulting in poor positioning accuracy. This equipment can only measure single points and requires manual placement of the product. Uneven coating of the bipolar plates can cause abnormal resistance, leading to insufficient data reliability. It is difficult to improve the process through data analysis. Manual placement of products typically takes about 30 minutes to measure 9 positions on a single product. Mass production limits capacity, resulting in low efficiency. Utility Model Content
