| 摘 要： | 研究了以Ce，Nd和Pr部分替代LaNi(3．5)Co(0.8)Mn(0.4)Al(0.3)中的La后对合金电化学及储氢特性的影响。稀土含量的变化明显改变合金的电化学及储氢特性。Pr对合金的电化学性能影响小于Ce。Ce使合金的放电容量降低，并升高合金的氢分解压。随着Nd含量的增加，合金的放电容量降低。

| Abstract: | The influence of Ce, Pr and Nd substituted for La in LaNi3.5 C%.8 Mn0.4A0.3 hydrogenstorage alloy on the electrochemical and hydrogen storage contents were studied. The resultshows that contents of rare earth component have a great effect on properties of the electrochemical and hydrogen storage. The influence of Pr on the electrochemistry of alloy electrode ismuch weak than Ce. But the discharge capacity of alloy electrode is decreased and the dissociation pressure of hydrogen is raised by Ce. The discharge capacity of alloy electrode decreaseswith increasing content of Nd. |
