Abstract
The present invention relates to a device and a method for detecting a pin hole in a part of a fuel cell stack part to accurately detect the presence of pin holes of stack parts thereby ensuring quality of a fuel cell stack. That is, the present invention provides a system for detecting a pin hole in parts of a fuel cell stack that allows for quality assurance of the fuel cell stack and prevents defective parts from being used, by examining each fuel stack part, which largely influence the quality of the fuel cell stack, using an X-ray device and a vision system, in order to determine the presence of a pin hole in the parts, and a method thereof.
