摘要：

La0.8Sr0.2MnO3 (LSM) and La0.8Sr0.2FeO3 (LSF) perovskites used as the anode materials for high temperature steam electrolysis (HTSE) were synthesized by sol-gel self-propagating method. These two powders were mixed with yttria-stabilized zirconia (YSZ) powders, respectively to fabricate composite anodes of solid oxide electrolysis cells (SOECs). The LSM-YSZ and LSF-YSZ composite anodes were tested at 1073 K SOEC working temperature under electrolysis conditions, using cells with a YSZ electrolyte and a Pt Counter electrode. Their electrochemical performances were compared and the possibilities of using as SOEC anodes were discussed. (c) 2008 Elsevier B.V. All rights reserved.
