Its electrolyte, typically yttria-stabilized zirconia (YSZ), is usually sintered above 1400 °C with commercially available powder materials. To lower the sintering temperature, yttria-doped bismuth oxide (YDB) is investigated in this work as an additive to form composite electrolytes. Dilatometric analysis reveals that the temperature corresponding to the maximum shrinkage rate is decreased from 1260 to 870 °C by YDB. Meanwhile, adding YDB results in the formation of poor conductive second phase monoclinic zirconia (m-ZrO<sub>2</sub>), especially when YDB content reaches 3 mol%. Thus, total conductivity decreases and then increases with YDB content. It is noted that the grain boundary conductivity is substantially improved, which is caused by bismuth enrichment at the grain boundary region of the dense composite electrolyte.</p>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"21 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141886892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, for the first time, we demonstrated the electrochemical promotion of complete methane oxidation over Pd at temperatures as low as 300 °C. The electrochemical promotion of Pd/YSZ was carried out at different cathodic and anodic polarization values in excess of oxygen (p<sub>O2</sub> = 6 kPa) in temperatures ranging from 300—420 °C. Upon anodic and cathodic polarization the highest rate increase of 17.7 and 1.4 was observed at 420 °C, respectively.
