| Outline of Final Research Achievements |
Mixed proton- and oxide ion conducting SOFCs can theoretically achieve higher voltage and resulting higher efficiency compared with conventional oxide ion-conducting SOFCs because of little or no dilution of fuel at the anode side. This study investigated electrolyte and electrode materials for realizing high efficiency mixed ion conducting SOFCs using methane. As a result, we revealed ionic transport property of Ba(ZrCeYYb)O3 and developed cathodes and anodes for mixed ion conducting SOFCs. An SOFC using developed components showed high open-circuit voltage with high power density. Also, we revealed keys for achieving high efficiency methane operation.
