| dc.description.abstractEn | Three selected materials have been prepared and shaped as cathode of half cells using the proton-conducting electrolyte BaCe<sub>0.9</sub>Y<sub>0.1</sub>O<sub>3 − δ</sub> (BCY10): two perovskite compounds, Ba<sub>0.5</sub>Sr<sub>0.5</sub>Co<sub>0.8</sub>Fe<sub>0.2</sub>O<sub>3 − δ</sub> (BSCF) and La<sub>0.6</sub>Sr<sub>0.4</sub>Fe<sub>0.8</sub>Co<sub>0.2</sub>O<sub>3 − δ</sub> (LSFC), and the praseodymium nickelate Pr<sub>2</sub>NiO<sub>4 + δ</sub> (PRN) having the K<sub>2</sub>NiF<sub>4</sub>-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 cm<sup>2</sup> 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. | |
