Selection and Evaluation Method of Hydrogen Production System in Hybrid Electrolytic Cell

  • 摘要: 电解槽是光伏电解水制氢技术的关键设备,其性能的优劣是影响制氢技术发展的关键因素。目前已被投入工程应用的电解槽有碱性电解槽(alkaline electrolyzer,AEL)和质子交换膜电解槽(proton exchange membrane electrolyzer,PEMEL),两类电解槽在经济性和技术性方面各有优劣。因此,提出混合电解槽应用技术。首先,提出层次分析-熵权法综合评估方法,按照所提方法求得混合电解槽系统最优选型;其次,将混合电解槽系统应用在光储耦合制氢系统中,并搭建其仿真模型;在此基础之上,进行3类电解槽多个性能指标对比分析。结果表明,混合电解槽成本为同容量PEMEL设备成本的56%,且混合电解槽电解效率可达91.5%,验证了所提方案的适用性。

     

    Abstract: Electrolytic cell is the key equipment of photovoltaic electrolysis water hydrogen production technology, and its performance is the key factor affecting the development of hydrogen production technology. Alkaline electrolyzer(AEL) and proton exchange membrane electrolyzer(PEMEL) have nowadays been used in engineering. The two kinds of electrolytic cells have advantages and disadvantages in economy and technology. Therefore, the application technology of hybrid electrolytic cell is put forward. Firstly, the comprehensive evaluation method of AHP and entropy weight method is proposed, and the optimal model of the hybrid electrolytic cell system is obtained according to the proposed method. Secondly, the hybrid electrolytic cell system was applied in the light-storage coupling hydrogen production system, and its simulation model was built. On this basis, multiple performance indexes of the three types of electrolytic cells were compared and analyzed. The results show that the cost of the hybrid electrolyzer is 56% of the equipment cost of the same capacity PEMEL, and the electrolytic efficiency of the hybrid electrolyzer can reach 91.5%, which proves the applicability of the proposed scheme.
