Abstract

Surface modification of La<inf>0.6</inf>Sr<inf>0.4</inf>Co<inf>0.2</inf>Fe<inf>0.8</inf>O<inf>3-δ</inf> (LSCF) was conducted by atomic layer deposition (ALD) with La<inf>0.6</inf>Sr<inf>0.4</inf>CoO<inf>3-δ</inf> (LSC). The anode supported cell with LSC modified LSCF cathode was used to analyze the effect of ALD LSC treatment. At the cell operating temperature (600°C) with the cell voltage of 550 mV, ALD treated cell has power density of 206.6 mW cm<sup>-2</sup> and showed increase in performance by 15.8 mW cm<sup>-2</sup> compared to bare cell. By analyzing the impedance results, it was found that both adsorption (or surface diffusion) and charge transfer kinetics were enhanced after ALD surface modification.
