High-entropy double perovskite SmBa(Mn0.2Fe0.2Co0.2Ni0.2Cu0.2)2O5+δ (HE-SBC) as a cathode material was prepared by a modified Pechini method, and the performance of HE-SBC with 10% (in mole fraction) Gd2O3-doped CeO2 (GDC) (HE-SBC-GDC) was optimized. The results show that the thermal expansion of Co ions caused by the change of valence state can be reduced due to the formation of high-entropy at B-site, thereby reducing the thermal expansion coefficient of SBC. The polarization impedance (Rp) of the HE-SBC symmetrical cell with yttria-stabilized zirconia (YSZ) as an electrolyte is 1.04 Ω·cm2 at 800 ℃ and the maximum power density and Rp of the anode-supported single cell are 683.53 mW/cm2 and 0.46 Ω·cm2, respectively. Furthermore, the catalytic activity of HE-SBC is improved by the addition of GDC[m(HE-SBC):m(GDC)=7:3] due to the enlarged three-phase interface. The polarization resistance of HE-SBC-GDC composite cathode symmetric cell is only 0.09 Ω·cm2 at 800 ℃ and the maximum power density and Rp of the anode-supported single cell are 838.66 mW/cm2 and 0.12 Ω·cm2, respectively.

通过改进的自蔓延燃烧法合成制备高熵双钙钛矿SmBa(Mn0.2Fe0.2Co0.2Ni0.2Cu0.2)2O5+δ(HE-SBC)阴极材料,并复合10%(摩尔分数)Gd2O3掺杂CeO2(GDC)以优化性能。结果表明:通过B位高熵的方法可以显著减小Co离子由价态变化而引起的热膨胀,从而降低SmBaCo2O5+δ的热膨胀系数。在800 ℃,以氧化钇稳定氧化锆(YSZ)为电解质的HE-SBC对称电池的极化阻抗(Rp)为1.04Ω·cm2,阳极支撑单电池的最高功率密度和Rp分别为683.53 mW/cm2和0.46Ω·cm2。进一步通过复合GDC(HE-SBC与GDC的质量比7:3)以增加三相界面提高HE-SBC的催化活性,在800 ℃ HE-SBC-GDC复合阴极对称电池的极化阻抗仅为0.09Ω·cm2,且阳极支撑单电池的最高功率密度和Rp分别为838.66 mW/cm2和0.12Ω·cm2。

通过改进的自蔓延燃烧法合成制备高熵双钙钛矿SmBa(Mn0.2Fe0.2Co0.2Ni0.2Cu0.2)2O5+δ(HE-SBC)阴极材料,并复合10%(摩尔分数)Gd2O3掺杂CeO2(GDC)以优化性能。结果表明:通过B位高熵的方法可以显著减小Co离子由价态变化而引起的热膨胀,从而降低SmBaCo2O5+δ的热膨胀系数。在800 ℃,以氧化钇稳定氧化锆(YSZ)为电解质的HE-SBC对称电池的极化阻抗(Rp)为1.04Ω·cm2,阳极支撑单电池的最高功率密度和Rp分别为683.53 mW/cm2和0.46Ω·cm2。进一步通过复合GDC(HE-SBC与GDC的质量比7:3)以增加三相界面提高HE-SBC的催化活性,在800 ℃ HE-SBC-GDC复合阴极对称电池的极化阻抗仅为0.09Ω·cm2,且阳极支撑单电池的最高功率密度和Rp分别为838.66 mW/cm2和0.12Ω·cm2。

High-entropy double perovskite SmBa(Mn0.2Fe0.2Co0.2Ni0.2Cu0.2)2O5+δ (HE-SBC) as a cathode material was prepared by a modified Pechini method, and the performance of HE-SBC with 10% (in mole fraction) Gd2O3-doped CeO2 (GDC) (HE-SBC-GDC) was optimized. The results show that the thermal expansion of Co ions caused by the change of valence state can be reduced due to the formation of high-entropy at B-site, thereby reducing the thermal expansion coefficient of SBC. The polarization impedance (Rp) of the HE-SBC symmetrical cell with yttria-stabilized zirconia (YSZ) as an electrolyte is 1.04 Ω·cm2 at 800 ℃ and the maximum power density and Rp of the anode-supported single cell are 683.53 mW/cm2 and 0.46 Ω·cm2, respectively. Furthermore, the catalytic activity of HE-SBC is improved by the addition of GDC[m(HE-SBC):m(GDC)=7:3] due to the enlarged three-phase interface. The polarization resistance of HE-SBC-GDC composite cathode symmetric cell is only 0.09 Ω·cm2 at 800 ℃ and the maximum power density and Rp of the anode-supported single cell are 838.66 mW/cm2 and 0.12 Ω·cm2, respectively.
