摘要

Quality checking electrode layers during the continuous manufacture of membrane electrode units (2) for fuel cells comprises using the homogeneity of fluorescing layers produced during anodic polarization in electrolytic solutions with electrochemically oxidizable additives with UV illumination as a measure for the homogeneity and quality of the electrode layers.
