Mitigating Electrolyte Flooding for Electrochemical CO₂Reduction via Infiltration of Hydrophobic Particles in a Gas Diffusion Layer

Wu, Yuming (author), Charlesworth, Liam (author), Maglaya, Irving (author), Idros, Mohamed Nazmi (author), Li, Mengran (author), Burdyny, T.E. (author), Wang, Geoff (author), Rufford, Thomas E. (author)

Achieving operational stability at high current densities remains a challenge in CO2 electrolyzers due to flooding of the gas diffusion layer (GDL) that supports the electrocatalyst. We mitigated electrode flooding at high current densities using a vacuum-assisted infiltration method to embed 200-400 nm-sized polytetrafluoroethylene (PTFE)...
