Oxygen Management in Ruthenium–Cerium Anode Facilitates Water Adsorption and Bubble Desorption for Oxygen Evolution at High Current Densities
The production of hydrogen via acidic water electrolysis requires efficient oxygen evolution reaction (OER) at high current densities. However, this is often limited by oxygen bubble accumulation, which blocks active sites and restricts water access. Although bubble release and water access are closely linked, these...
