Use Case Electrodes
Drying Status
Areal Capacity
Drying status over time as well as areal capacities of electrode ink or pastes deposited on substrates were derived by complex eddy current impedance.
Use Case Carbon Non Woven Gas Diffusion Layer for PEM
Areal Weight
Due to the anisotropic behavior of carbon fiber filaments high frequency eddy current technology enables characterization of carbon non woven gas diffusion layer for PEM fuel cells.
Use Case Carbon Based Bipolar Plates
Sheet Resistance
Sheet resistance of bipolar half plate bulk material is characterized by high frequency eddy current imaging solutions. The carbon plate bulk material was kindly provided by the Open Source Stack initiative of the Innovation Cluster HZwo e.V.. Flow field water jet cutting process was applied by NOVAJET GmbH.
