Electrochemical properties of perovskite and A<sub>2</sub>MO<sub>4</sub> -type oxides used as cathodes in protonic ceramic half cells
Three selected materials have been prepared and shaped as cathode of half cells using the proton-conducting electrolyte BaCe0.9Y0.1O3 â ÎŽ (BCY10): two perovskite compounds, Ba0.5Sr0.5Co0.8Fe0.2O3 â ÎŽ (BSCF) and La0.6Sr0.4Fe0.8Co0.2O3 â ÎŽ (LSFC), and the praseodymium nickelate Pr2NiO4 + ÎŽ (PRN) having the K2NiF4-type structure. The electrochemical properties of these compounds have been studied under zero current conditions (two-electrode cell) and under polarization (three-electrode cell). Their measured area-specific resistances were about 1-2 Ω cm2 at 600 °C. Under direct current polarization, it appears that the three compounds show almost similar values of current densities at 625 °C; however, at lower temperatures, BSCF appears to be the most efficient cathode material
