Huei-Ru “Molly” Jhong, Fikile R. Brushett and Paul J. A. Kenis The Effects of Catalyst Layer Deposition Methodology on Electrode Performance Advanced Energy Materials 3
The effects of catalyst layer deposition methods on electrode performance for fuel cells and CO2 electrolysis cells are investigated. Micro-computed X-ray tomography is employed to visualize and quantify the structure of the catalyst layer in 3D and over a large geometric area. By coupling structural analysis with in situ electrochemical characterization, changes in electrode performance can be directly correlated to differences in catalyst layer structure, which in turn can guide electrode optimization, including improved catalyst utilization.
