Performance of reversible solid oxide cells based on La0.6Ca0.4Fe0.7Sc0.1Ni0.2O3−δ oxygen electrode

Funds: The project was supported by National Key R&D Program of China (2021YFE0100200), National Natural Science Foundation of China (52172199), Fundamental Research Funds for the Central Universities (2021QN1111), Open Sharing Fund for the Large-scale Instruments and Equipments of China University of Mining and Technology(DYGX-2021-026)
  • 摘要: 本研究制备了10% Sc掺杂的La0.6Ca0.4Fe0.7Sc0.1Ni0.2O3−δ (LCFSN)材料,采用半电池研究了该材料的氧还原催化活性(ORR)和氧析出催化活性(OER),发现LCFSN的ORR催化活性优于OER催化活性。组装了Ni-YSZ((Y2O3)0.08(ZrO2)0.92)/YSZ/GDC(Gd0.1Ce0.9O2−δ)/LCFSN全电池并研究了其在燃料电池模式(SOFC)和电解池模式(SOEC)下的电化学性能,电池在800 ℃以H2为燃料时的最高功率密度可达1.471 W/cm2,在750 ℃,50%H2O和1.3 V热中性电解电压条件下其产氢速率高达627 mL/(cm2·h)。而且电池在100 h的稳定性测试中性能没有衰减,具有良好的稳定性。通过研究,证明了LCFSN是一个具有良好发展前景的氧电极材料。
