Efficient catalysts are imperative to accelerate the slow oxygen reaction kinetics for development of emerging electrochemical energy systems ranging from room-temperature alkaline water electrolysis high-temperature ceramic fuel cells. In this work, we reveal role cationic inductive interactions in predetermining vacancy concentrations 235 cobalt-based and 200 iron-based perovskite at different temperatures, trend can be well predicted machine learning techniques based on lattice...
Abstract Protonic ceramic cells show great promises for electrochemical energy conversion and storage, while one of the key challenges lies in fabricating dense electrolytes. Generally, poor sinterability most protonic electrolytes, such as BaZr 0.1 Ce 0.7 Y Yb O 3‐δ , is attributed to Ba evaporation at high temperatures. In a systematic comparative study BaCeO 3 BaZrO results demonstrated that tends segregate grain boundaries rather than evaporate. Additionally, thermal reduction 4+ 3+...
Comparing symmetric cells with oxygen-ion and protonic conductive electrolytes, using distinct electrodes, shows that electrode hydration strongly affects proton-conductivity in defective perovskite electrolytes.
Abstract Protonic ceramic fuel cells (PCFCs) are one of the promising routes to generate power efficiently from various fuels at economically viable temperatures (500–700 °C) due use fast proton conducting oxides as electrolytes. However, density and durability PCFCs still limited by their cathodes made solid metal oxides, which challenging address sluggish oxygen reduction reaction susceptibility CO 2 simultaneously. Here, an alternative approach is reported this challenge developing a new...
Solid oxide fuel cells (SOFCs) offer promising prospects for sustainable electricity generation, attributed to high efficiency and adaptability. However, their widespread application relies on three critical factors: performance, cost-effectiveness, durability. Durability presents a significant hurdle; one key reason is the thermal expansion mismatch between cobalt-based cathodes electrolytes, potentially leading detachment at cathode-electrolyte interface. In this study, we propose an...
