Interfacial resistance can be measured using various techniques:
1. Electrochemical Impedance Spectroscopy (EIS): This technique measures the impedance of a system over a range of frequencies, providing insights into the interfacial resistance. 2. Contact Angle Measurement: This method evaluates the wettability of the catalyst surface, which can be related to interfacial resistance. 3. Surface Characterization Techniques: Methods such as Scanning Electron Microscopy (SEM) and Atomic Force Microscopy (AFM) can provide information about the surface morphology and roughness, which are related to interfacial resistance.
