AB5型固态金属储氢系统吸放氢特性实验研究
摘要：摘要为研究AB5型固态金属储氢系统在不同温度和压力条件下的吸/放氢性能,搭建小型固态金属储氢罐实验平台,设计不同温度及压力条件下的吸/放氢循环实验,利用循环水浴系统构造换热环境对固态金属储氢罐进行循环换热,测试吸/放氢压力和温度等关键操作参数对AB5型固态金属储氢系统吸/放氢性能的影响。结果表明：在达到相应吸氢反应平衡压力的条件下,较高的吸氢压力和温度对吸氢效率均具有促进作用,同时,较高的吸氢压力会加剧系统主要吸氢阶段的化合反应,伴有强烈的热交换行为,且维持不同放氢压力条件下的持续放氢需达到相应的放氢温度;同一压力条件下,较高的放氢温度可提高系统的放氢效率,使系统内部氢气压差达到相应放氢条件以维持系统持续稳定放氢的需求。上述结论可为AB5型固态金属储氢系统的研究提供参考。
Abstract:：To study the performance of hydrogen absorption/desorption of AB5 solid metal hydrogen storage system under different temperatures and pressures, an experimental platform with a small solid metal hydrogen storage tank was established, and hydrogen absorption/desorption cycling experiments under different temperatures and pressures were designed. A circulating water bath system was used to construct a heat exchange environment to circulate the heat to the solid metal hydrogen storage tank, and to test the influences of the key operating parameters, such as the pressure and temperature of hydrogen absorption and desorption, on the performance of hydrogen absorption/desorption of the AB5 solid metal hydrogen storage system. The results show that higher hydrogen absorption pressures and temperatures can promote hydrogen absorption efficiency under the corresponding hydrogen absorption equilibrium pressures. At the same time, higher hydrogen absorption pressures exacerbate the chemosynthesis reactions in the main hydrogen absorption phase of the system, resulting in a strong heat exchange behavior, and maintaining continuous hydrogen desorption at different release pressures requires the appropriate desorption temperature. Under the same pressure conditions, a higher hydrogen desorption temperature increases the hydrogen desorption efficiency of the system, so that the pressure difference of hydrogen inside the system can meet the requirements of the corresponding hydrogen desorption conditions to maintain continuous and stable hydrogen desorption. The above conclusions can provide a reference for studying AB5 type solid metal hydrogen storage systems.
