Enhancement of La0.6Sr0.4Co0.2Fe0.8O3-δ durability and surface electrocatalytic activity by La0.85Sr0.15MnO3±δ investigated using a new test electrode platform†
Abstract
A carefully designed test cell platform with a new electrode structure is utilized to determine the intrinsic surface catalytic properties of an electrode. With this design, the electrocatalytic activity and stability of an La0.6Sr0.4Co0.2Fe0.8O3−δ (LSCF) cathode is enhanced by a dense thin La0.85Sr0.15MnO3±δ (
