Experimental behaviour of a three-stage metal hydride hydrogen compressor
摘要：
建立了一台以AB 2型合金为基础的三级金属氢化物氢压缩机系统。每个阶段都可以被认为是Sieverts型装置。MHHC系统可以分别在真空至250巴和RT至200 ℃的压力和温度范围内工作。在设计的工作温度范围内建立了有效的热管理系统。它转储温度变化，由于氢膨胀阶段耦合和合金中的氢吸收/解吸。每个反应器由一个单一的薄不锈钢管，以最大限度地提高传热。它们填充有相似量的AB 2合金。MHHC系统能够产生高达84.7的压缩比（CR），入口和出口氢气压力为1.44巴和122巴，温度跨度为23至120 ℃。
英文摘要：
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.
