AB  - In polymer electrolyte membrane (PEM) water electrolysis the activematerial component is the membrane electrode assembly (MEA)consisting of a cathode and an anode catalyst layer (CL) coated on aproton conducting membrane.During large-scale MEA production critical process steps are thetemperature treatment (tempering) of CLs and the CL decal transfer onto the membrane as they have a great impact on electrodeconductivity, which is an important factor in MEA performance.To monitor the quality of these production steps a fast and reliablein-line analysis tool needs to be established. This becomes especiallyimportant as the production volume is increasing towards the GWscale. Here, we propose the eddy current technique for in-linequality control. It is an inductive, non-destructive method andprovides fast and accurate sheet resistance information.
