LaCrO3-Coated La0.6Sr0.4Co0.2Fe0.8O3−δ Core–Shell Structured Cathode with Enhanced Cr Tolerance for Intermediate-Temperature Solid Oxide Fuel Cells
Source abstract
Abstract
La0.6Sr0.4Co0.2Fe0.8O3−δ (LSCF) is a common cathode material for intermediate-temperature solid oxide fuel cells because of its excellent oxygen reduction reaction catalytic activity. However, the Cr-poisoning effect is a severe issue, causing electrochemical performance degradation. For the development of a LSCF-based cathode with excellent Cr tolerance, a LaCrO3-coated LSCF core–shell structured (LCr@LSCF) cathode was prepared via the solution infiltration method. After the cathode was coated with a LCr shell, the long-term stability and Cr tolerance were obviously improved, at the price of sacrificing some electrochemical performance. The development of a LCr@LSCF cathode with eye-catching Cr tolerance is of great significance to the commercialization of LSCF.
