Reliability of an All Perovskite-Based Solid Oxide Fuel Cell

A solid oxide fuel cell (SOFC) has been manufactured using a Ni-modified perovskite and perovskite-based electrolyte and cathode. The SOFC has been investigated for operation at intermediate temperatures. In this regard, we have first studied the electrical properties of La0.8Sr0.2Ga0.8Mg0.2O3 (LSGM) and gadolinia-doped ceria (GDC) electrolytes and afterwards we have investigated the reliability of the Ni-modified La0.6Sr0.4Fe0.8Co0.2O3 based anode operation in combination with LSGM electrolyte and La0.6Sr0.4Fe0.8Co0.2O3 (LSFC) cathode. A 50 h electrochemical test for the SOFC operation under different fuel feed is presented to show the reliability characteristics of such SOFC architecture.
