Aspects of the present invention include a porous ceramic cathode, optionally a cathode three-layer interface layer, a two-layer electrolyte including a layer containing cerium oxide and a layer containing bismuth oxide, an anode functional layer, and a porous ceramic having electrical interconnections The present invention relates to a SOFC having a multilayer structure including an anode, and the SOFC has a very high power density at a temperature lower than 700 ° C. using hydrogen fuel or hydrocarbon fuel. The conversion of chemical energy to electrical energy at low temperatures allows the production of fuel cells using stainless steel or other metal alloys in the interconnect instead of ceramic conductive oxides. |
