Abstract Protonic ceramic cells (PCCs) have gained significant attention as a promising electrochemical device for hydrogen production and power generation at intermediate temperatures. However, the lack of high‐performance air electrodes, specifically in terms proton conduction ability, has severely hindered improvement performances PCCs. In this study, high‐efficiency electrode La 0.8 Ba 0.2 CoO 3 (LBC) is rationally designed researched by machine‐learning model density functional theory (DFT) calculation, which boosts Specifically, an elements‐property map designing oxides created predicting studying uptake ability 1– x A′ BO (A′ = Na, K, Ca, Mg, Ba, Cu, etc.) eXtreme Gradient Boosting model. PCC with LBC yields high current destiny electrolysis mode (1.72 A cm −2 600 °C) fuel cell (1.00 W °C). addition, ultra‐low reaction resistance (0.03 Ω 2 achieved, because can significantly facilitate formation O * . This work not only reports effective but also presents new avenue rational design electrodes
