论文摘要
已经建立了基于AB2型合金的三阶段金属氢化氢压缩机（MHHC）系统。每个阶段都可以视为Sieverts型设备。 MHHC系统可以在从真空到250 bar和RT到200C的压力和温度范围内工作。为设计的温度范围建立了有效的热管理系统。由于阶段耦合期间氢的膨胀以及合金中的氢吸收/解吸，它会倾倒温度变化。每个反应器由单个和细的不锈钢管组成，以最大程度地传热。它们充满了类似数量的AB2合金。对于入口和出口氢压为1.44和122 bar的MHHC系统能够产生高达84.7的压缩比（CR），温度跨度为23至120c。
A three-stage metal hydride hydrogen compressor (MHHC) system based in AB2-type alloys has been set-up. Every stage can be considered as a Sieverts-type apparatus. The MHHC system can work in the pressure and temperature ranges comprised from vacuum to 250 bar and from RT to 200C, respectively. An efficient thermal management system was set up for the operational ranges of temperature designed. It dumps temperature shifts due to hydrogen expansion during stage coupling and hydrogen absorption/desorption in the alloys. Each reactor consists of a single and thin stainless-steel tube to maximize heat transfer. They are filled with similar amount of AB2 alloy. The MHHC system was able to produce a compression ratio (CR) as high as of 84.7 for inlet and outlet hydrogen pressures of 1.44 and 122 bar for a temperature span of 23 to 120C.
