Enhancing Oxygen Reduction Activity and Cr Tolerance of Solid Oxide Fuel Cell Cathodes by a Multiphase Catalyst Coating

Yinghua Niu et al.

Summary: Intermediate temperature solid oxide fuel cells (IT-SOFCs) face challenges due to the sluggish oxygen reduction reaction (ORR) and cathode degradation. A highly efficient multiphase catalyst coating significantly enhances the ORR activity and durability. Experimental results show improved peak power density and increased durability against Cr and H2O. Both the BCFN phase and BaCO3 phase contribute to the improved performance of the LSCF cathode.

Enhanced La0.6Sr0.4Co0.2Fe0.8O3-δ-based cathode performance by modification of BaZr0.1Ce0.7Y0.1Yb0.1O3-δ electrolyte surface in protonic ceramic fuel cells

Hiroyuki Shimada et al.

Summary: By modifying the cathode/electrolyte interface with a porous BZCYYb interlayer (PBI) in PCFCs, the cathode performance has been significantly improved, achieving high power density at lower temperatures. The use of this interlayer enhances the cathode/electrolyte interfacial structure and increases the triple-phase boundary, resulting in improved overall performance of the fuel cell.
