Abstract

Ce_0.6Mn_0.3Fe_0.1O_2-δ (CMF) has been used as a new oxide cathode of solid oxide electrolysis cell (SOEC) using LaGaO₃-based electrolyte for H₂ production under a feeding gas composition of 20%steam/1%H₂/79%Ar. CMF cathode exhibits good electrolysis performance and well-performed hydrogen production rate with the Faraday's law at 1173-973 K. Through impedance measurement under a DC polarized condition, the studies show that polarization resistance and ohmic resistance decreased with increasing DC bias potential. Furthermore, CMF showed good stability, and no significant aggregation and delamination were noticed during the electrolysis measurement. These results suggest that CMF can be a promising oxide cathode candidate for intermediate temperature SOEC.
