Cobalt-Based Perovskite Electrodes for Solid Oxide Electrolysis Cells

Recently, many efforts and much attention has been paid to developing environmentally friendly energy. Solid oxide electrolyte cells (SOECs) process in reverse solid fuel (SOFCs) producing hydrogen gas as a green energy source. However, this application, high-performance catalysts are usually required overcome the sluggish oxygen evolution reactions (OER) during water decomposition. For reason, discovery of with high performance is crucial issue for wide application SOECs. Owning their inherent activity adequate stability electrochemical conditions, perovskite oxides have intensively employed In mini review, we summarize currently available studies concerning applications cobalt-based Particularly, structural properties corresponding electronic structures discussed based on performance, both experimentally theoretically.
