DEVELOPMENT OF HIGHLY ACTIVE AND STABLE (Gd,Ce)O2-IMPREGNATED (La,Sr)MnO3 ANODES OF SOLID OXIDE ELECTROLYSIS CELLS
High temperature solid oxide electrolysis cell (SOEC) has a great potential for efficient and economic production of hydrogen fuel as it involves less electrical energy consumption compared to conventional low temperature water electrolysis. However, one of the major problems for the long-term stability of an SOEC is the degradation and delamination of the anodes due to the high oxygen partial pressure generated at the interface. Here, we report the development of highly active and structurally stable anodes based on the Gd0.2Ce0.8O1.9 (GDC)-impregnated La0.8Sr0.2MnO3 (LSM) anodes. The results show that the GDC-impregnation not only enhances the electrocatalytic activities for the O2 oxidation reaction, but also effectively inhibits the delamination of the LSM anode at the interface. The results demonstrate the promising potential of the GDC-impregnated LSM as the effective and stable anodes of SOECs.
