The invention provides a stacked fuel cell membrane electrode MEA pole position detection method, which comprises the following steps: S1, fixing a membrane electrode of a fuel cell, and shooting the membrane electrode to obtain an image for detection; s2, inputting the detection image into a computer vision image recognition module for recognition, and outputting the position of the membrane electrode in the fuel cell by the computer vision image recognition module; and S3, comparing the identified position with a standard membrane electrode position to calculate a deviation value, if the deviation value is smaller than a threshold value, outputting a conclusion that the fuel cell membrane electrode is qualified, otherwise, outputting a conclusion that the fuel cell membrane electrode is unqualified. According to the scheme, the infeasibility of manual naked eye recognition is solved, and the recognition accuracy and speed are also ensured due to the adoption of an advanced computer vision recognition algori
