Thermal-expansion offset for high-performance fuel cell cathodes

Yuan Zhang et al.

Summary: This study demonstrates an approach to achieving full thermo-mechanical compatibility between the cathode and other cell components for solid oxide fuel cells. By introducing a thermal-expansion offset and using reactive sintering to form a composite electrode, the research shows high activity and excellent stability of the electrode. The introduction of reactive negative-thermal-expansion components may provide a general strategy for developing fully compatible and highly active electrodes for SOFCs.

Electrical Properties of Ce0.8Dy0.175Ca0.025O2-δ

S. Ramesh

Summary: The present paper focuses on the structure, microstructure, and electrical properties of Ca- and Dy-doped ceria electrolyte materials. The CaDDC sample prepared through a modified sol-gel low-temperature process showed improved oxygen vacancies, dense surface, and enhanced conductivity. Impedance spectroscopic studies revealed migration energy, association energy, and relaxation peaks, indicating a reorientation of defect associates in the sample. The Ce0.8Dy0.175Ca0.025O2-delta sample exhibited improved conductivity and activation energy.
