Abstract:
By forming a structure wherein an oxygen ionic conductor or a mixed ionic-electronic conductor (MIEC) on a cathode surface is not covered by a molten carbonate electrolyte using an oxygen ionic conductor or a mixed ionic-electronic conductor having poor wettability on the molten carbonate electrolyte, a new electrochemical reaction site may be provided in addition to that provided by the molten carbonate electrolyte. As a result, cell performance, particularly cathode performance, can be improved even at low operation temperatures (e.g., 500-600° C.).
