浓差电池
3)  oxygen concentration cell
氧浓差电池
1.

结果表明,氧浓差电池电动势的实测值与理论值吻合得很好,氧离子迁移数为1,表明该陶瓷样品在该温度下氧气气氛中为一纯氧离子导体;氧泵(氧的电化学透过)实验结果进一步证实了该样品在氧气气氛中为一纯氧离子导体;在氧分压p(O2)=10-5~105Pa的高氧分压气氛中,电导率与氧分压变化基本无关,表明在该氧分压范围内样品为纯离子导体,这与氧浓差电池电动势测定结果相吻合;在低氧分压为10-5~10-15Pa范围内,总电导率随氧分压降低而稍有升高,表明在该氧分压范围样品为氧离子与电子的混合导体;在600~1000℃下氧离子电导率>10-2S?cm-1,显著高于母体La2Mo2O9的氧离子电导率,1000℃时的氧离子电导率为0。

补充资料:无迁移浓差电池
分子式:
CAS号:

性质:浓差电池的一种,实为两个电池对接,避免了液接电势,故是可逆的。例如,Pt/H2(p1)/HCl(m1)/AgCl/Ag/AgCl/HCl(m2)/H2(p2)/Pt及Ag/AgCl/KCl(m1)/K(Hg)/KCl(m2)/AgCl/Ag等。从其电动势可算得溶液中离子或汞齐电极中金属的活度系数等热力学参数。
