Abstract
A method for measuring a plate for a fuel cell stack includes providing a model of the plate including a first axis and a second axis. The model has at least one theoretical measurement feature with a theoretical set of coordinates. The plate is also provided with at least one measurement feature. The first axis and the second axis are established relative to the plate. The at least one measurement feature of the plate is then located relative to the first axis and the second axis. The at least one measurement feature is measured to determine a first set of coordinates for the at least one measurement feature. The first set of coordinates of the plate is compared to the theoretical set of coordinates of the model to determine a displacement of the first set of coordinates from the theoretical set of coordinates.
