Abstract:

Solid oxide electrolysis cells (SOECs) have stimulated wide interests for their promising application in the reduction of CO2 emissions and the storage of renewable energy. Here, the advances made in the development of cathode materials including cermets and perovskite oxides in our research group, are summarized, along with the design of cell configurations. The electrochemical kinetics and performances of cathodes and cells are discussed and analyzed. It is expected that this brief review offers critical insights and useful guidelines for developing superior electrodes and SOECs in the future.

Key words: solid oxide electrolysis cells, CO2 reduction, cathodes, cermets, perovskites
