In the present work, an experimental investigation is carried out to study the absorption and desorption characteristics of a metal hydride reactor filled with 1.4 kg of La_0.9Ce_0.1Ni₅. A simple tubular reactor with an outer cooling jacket was fabricated. The effects of supply pressure and absorption temperature on hydriding rate and the effect of desorption temperature on dehydriding rate were analyzed. From the parametric study, it is observed that the supply pressure has a substantial effect on the amount of hydrogen absorbed than that of absorption temperature. The amount of hydrogen absorbed was increased by 45% when supply pressure was increased from 10 to 30 bar, whereas the same was increased by only 6.6% when the absorption temperature was decreased from 20°C to 10°C. The increment in the desorbed mass of hydrogen was 20.4% when desorption temperature was increased from 70°C to 90°C. To accelerate the desorption process, intermediate sensible heating was carried out. After 50 cycles of operation under different conditions, the amount of hydrogen absorption was dropped from 19.1 to 15.52 g at a supply pressure of 40 bar, whereas the amount of hydrogen desorption was decreased from 13.8 to 10.5 g at the desorption condition of 70°C.

La0.9Ce0.1Ni5在储氢中的吸附与解吸特性的实验研究。

在目前的工作中，进行了实验研究以研究填充有1.4 kg La _0.9 Ce _0.1 Ni ₅的金属氢化物反应器的吸收和解吸特性。。制造了具有外部冷却套的简单管式反应器。分析了供给压力和吸收温度对氢化率的影响以及解吸温度对脱水率的影响。从参数研究中可以看出，供给压力对氢吸收量的影响比吸收温度的影响大。当供应压力从10 bar增加到30 bar时，氢吸收量增加了45％，而当吸收温度从20°C降低到10°C时，氢吸收量仅增加了6.6％。当解吸温度从70℃增加到90℃时，氢的解吸质量的增加为20.4％。为了加速解吸过程，进行了中显热。
