Optimization of cathode catalyst layer of membrane electrode assembly for polymer electrolyte fuel cells using machine learning

In situ 3D X-ray imaging of water distribution in each layer of a membrane electrode assembly of a polymer electrolyte fuel cell

“…Mass transport simulations have been applied to elucidate the transient movement of water, 36 but realistic large-scale simulations still have difficulties in reproducing the characteristics of electrochemical operations and the complex structures inside PEFCs. 37 The current approach based on 3D X-ray CT imaging and statistical analysis has successfully clarified not only the differences in water distributions between each layer of the PEFC but also the significant changes in water drainage under PEFC power generation conditions for the first time.…”
