A brief review of conductivity and thermal expansion of perovskite-related oxides for SOFC cathode

Eurasian Journal of Physics and Functional Materials, 2021
Cathode materials with mixed ion-electron conductivity (MIEC) are necessary for the development of low or intermediate temperature solid oxide fuel cells. Perovskite and perovskite-related materials are promising candidates on this role.

High Power Density, Low Temperature, Solid Oxide Fuel Cells at Elevated Oxygen Partial Pressure

Advanced Energy Materials, EarlyView.
Elevated pO2${{p}_{{{{\mathrm{O}}}_2}}}$ improves oxygen reduction reaction (ORR) kinetics, thus reducing electrode area specific resistance (ASR). The effect of pO2${{p}_{{{{\mathrm{O}}}_2}}}$ in open circuit potential (OCP) and ASR is demonstrated on both Sr0.5Sm0.5CoO3‐δ‐Gd0.1Ce0.9O2‐δ (SSC‐GDC) composite cathodes and our recently developed nano‐PSC

Fabrication of BaZr0.1Ce0.7Y0.1Yb0.1O3‐δ Skeleton Structure for the Development of High‐Performance Nanocomposite Cathodes for Protonic Ceramic Fuel Cells by Nitrate Impregnation

Small, EarlyView.
A homologous BZCYYb1711 cathode skeleton was constructed using the same material as the electrolyte, and active components were introduced into the skeleton via nitrate impregnation to form a nanocomposite cathode. This strategy effectively alleviated the thermal expansion coefficient (TEC) mismatches between the cathode and electrolyte.

Quasi‐In Situ 4D‐STEM Mapping of Exsolution Driven Parent Matrix Restructuring in Sr2FeMoO6‐δ

Small Methods, EarlyView.
How does catalytic exsolution alter its parent matrix in realistic solid oxide cells? A beam‐artifact‐free, quasi‐in situ 4D‐STEM methodology maps intrinsic nanoscale transformations in bulk Sr2FeMoO6‐δ electrodes. Correlative identical‐location imaging reveals that surface exsolution inherently couples with profound crystallographic reorganization and
