摘要
The electrochemical properties of La 0.5 Sr 0.5 Co 0.8 M 0.2 O 3–δ (M=Mn, Fe, Ni, Cu) cathodes are investigated with chemical bulk diffusion coefficients ( D chem ) and polarization resistances. The electrochemical performance of long‐term testing for La 0.5 Sr 0.5 Co 0.8 Cu 0.2 O 3–δ cathode was carried out to investigate its electrochemical stability. In this work, an anode‐supported single cell with a thick‐film SDC electrolyte (30 μm), a Ni‐ SDC cermet anode (1 mm), and a La 0.5 Sr 0.5 Co 0.8 Cu 0.2 O 3–δ cathode (10 μm) reaches a maximum peak power density of 983 mW/cm 2 at 700°C. Obviously, Cu substitution for B‐site of La 0.5 Sr 0.5 CoO 3–δ cathode reduced thermal expansion coefficient ( TEC ) value and enhanced oxygen bulk diffusion and electrochemical properties. La 0.5 Sr 0.5 Co 0.8 Cu 0.2 O 3–δ is a promising cathode material for intermediate temperature solid oxide fuel cells ( IT ‐ SOFC ).
