Abstract

The hydrogen sorption characteristics of La_1–xCe_xNi₅ alloys (x = 0, 0.1, 0.2, 0.25, 0.5) were studied in the temperature range 298–363 K. The optimal compositions of intermetallic compounds were determined for use as hydrogen sorbents in reusable accumulators: compounds La_0.9Ce_0.1Ni₅ and La_0.8Ce_0.2Ni₅. Based on them, a metal hydride hydrogen accumulator was designed and manufactured and its technical and operational characteristics were found. The developed devices are proposed to be applied in electric energy storage systems using hydrogen as an energy carrier.

摘要

研究了La _{1– x} Ce _x Ni ₅合金（x = 0、0.1、0.2、0.25、0.5）在298–363 K温度范围内的氢吸附特性。确定了用作氢的最佳金属间化合物组成可重复使用的蓄电池中的吸附剂：化合物La _0.9 Ce _0.1 Ni ₅和La _0.8 Ce _0.2 Ni ₅。在此基础上，设计制造了一种金属氢化物储氢器，并找到了其技术和运行特性。拟将开发的设备应用于以氢为能量载体的电能存储系统。
