Accelerated Discovery of Proton-Conducting Perovskite Oxide by Capturing Physicochemical Fundamentals of Hydration

Junji Hyodo et al.

Summary: Accelerated discovery of a proton-conducting oxide was demonstrated using data-driven structure-property maps for hydration of hypothetical perovskite oxides. This approach involved constructing trustworthy hydration training data sets and knowledge-based target variable engineering to achieve high accuracy in predicting proton concentration against temperature in unknown compositions extrapolated from the training data sets. The results are promising for speeding up the development and applications of proton-conducting oxides.

Metal/Oxide Heterojunction Boosts Fuel Cell Cathode Reaction at Low Temperatures

SeongWoo Jeong et al.

Summary: This research clarifies the mechanism of promoting cathode reactions on proton-conducting ceramics at low temperatures by blocking oxide ion conduction to enhance proton transfer, reducing cathode polarization resistance in HMFCs. The study reveals that increased interfacial proton concentration gradient leads to more efficient utilization of overpotential in HMFCs.

Transition from perovskite to misfit-layered structure materials: a highly oxygen deficient and stable oxygen electrode catalyst†

Muhammad Saqib et al.

Summary: A novel misfit-layered compound GCCCO has been reported as a superior and durable bifunctional oxygen electrode material for RPCCs, showing high power densities and current densities. The superior catalytic performances of GCCCO are attributed to its oxygen defect rich structure, triple conducting property, needle-like grain morphology, and suitable thermal expansion coefficient.
