Components for the manufacture of polymer electrolyte membrane fuel cells are provided, as well as apparatus and automatable methods for their manufacture by rotary die cutting and by lamination of various layers to form membrane electrode assemblies. Such a correction provides for a more accurate calibration of the linewidth measurement tool and a more accurate measurement of linewidths within microelectronic products while employing the calibrated linewidth measurement tool. By means of the method of the invention it is possible to classify wines by sort of wine, growing regions, grape, vine, vintage, kind of material or wood of the wine cask used, and varying degree of maturity of the wine, and by other chemical parameters.
