PRODUCTION METHOD AND PRODUCTION SYSTEM FOR PRODUCING A FUEL CELL STACK

WIPO Patent Application WO/2023/198490

A3

The present invention relates to a production method (100) for producing a fuel cell stack. The production method (100) comprises: manufacturing (101) a number of fuel cells in a manufacturing line (201) by means of a plurality of manufacturing steps; determining (103) voltage values of a voltage of a respective fuel cell of the number of fuel cells from a start point, at which a supply of fuel to the fuel cell is interrupted, to an end point; assigning (105) the voltage values to a first group which describes a fault-free state of the fuel cell, or to a second group which describes a faulty state of the fuel cell, by means of a machine learner; rejecting (107) fuel cells whose voltage values are assigned by the machine learner to the second group; and combining (109) only fuel cells whose voltage values were assigned by the machine learner to the first group to form a fuel cell stack.
