알칼리용액에서 La0.8Sr0.2MnO3 페롭스카이트 촉매의 산소환원 및 발생반응에서 도전재의 영향 = Effect of Conductive Additives in La0.8Sr0.2MnO3 Perovskite Electrodes for Oxygen Reduction and Evolution in Alkaline Solution

다국어 초록 (Multilingual Abstract)

The effects of conductive additives in a La0.8Sr0.2MnO3 perovskite bifunctional electrode for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) were investigated in an alkaline solution. Highly porous carbon black (CB) and Ni powder were added to the bifunctional electrodes as conductive additives. The surface morphologies of electrodes containing CB and Ni were observed by scanning electron microscopy (SEM).
The current densities for both ORR and OER were changed by the addition of CB. The conductive additive changed physical properties of bifunctional electrodes such as the sheet conductance, gas permeability and contact angle. It was observed that the air permeability of electrode was most effective to enhance the currents for ORR and OER.
