Abstract

This paper presents the performance and behavior of a novel system of integration of an anion exchange membrane (AEM) based water electrolyzer (AEMWE) and fuel cell (AEMFC) with solar photovoltaic (PV) cell and steam turbine unit (STU) for the generation of green hydrogen and uninterrupted electricity production. Based on the sensitivity analyses, the optimized operating parameters of AEMWE were found as 7300 kW input load, 50 μm membrane thickness, and 90 ^oC operating temperature. The energy analysis was carried out for various configurations of the cases, (i) AEMWE & AEMFC, (ii) AEMWE, AEMFC & STU, and (iii) solar PV cell, AEMWE, AEMFC & STU using Aspen plus for 100 kg/h of hydrogen output. The energy assessment of the integrated AEMWE with AEMFC (case i) showed the highest net efficiency of 45.5 %, whereas using a hydrogen furnace for steam generation (case ii) the net efficiency has decreased to 35.9 %. With the use of solar energy (case iii) with AEMWE, the overall energy efficiencies have been found to range between 7.33 and 8.21 %.

以阴离子交换膜为基础的水电解槽和燃料电池的太阳能集成，用于不间断的氢气和发电

本文介绍了一种基于阴离子交换膜（AEM）的水电解槽（AEMWE）和燃料电池（AEMFC）与太阳能光伏电池（PV）和蒸汽轮机（STU）集成的新型系统的性能和行为，用于绿色氢的产生和不间断电力生产。通过灵敏度分析，确定了AEMWE的最佳工作参数为输入负载7300 kW，膜厚50 μm，工作温度90 oC。对不同配置的箱体进行了能量分析，(1)AEMWE &；AEMFC, (ii) AEMWE, AEMFC &；（iii）太阳能光伏电池，AEMWE, AEMFC &；STU使用Aspen plus进行100公斤/小时的氢气输出。综合AEMWE与AEMFC（案例i）的能源评估显示净效率最高，为45.5%，而使用氢炉产生蒸汽（案例ii）的净效率下降至35.9%。在AEMWE中使用太阳能（案例iii），发现整体能源效率在7.33%至8.21%之间。

期刊介绍： The objective of the International Journal of Hydrogen Energy is to facilitate the exchange of new ideas, technological advancements, and research findings in the field of Hydrogen Energy among scientists and engineers worldwide. This journal showcases original research, both analytical and experimental, covering various aspects of Hydrogen Energy. These include production, storage, transmission, utilization, enabling technologies, environmental impact, economic considerations, and global perspectives on hydrogen and its carriers such as NH3, CH4, alcohols, etc. The utilization aspect encompasses various methods such as thermochemical (combustion), photochemical, electrochemical (fuel cells), and nuclear conversion of hydrogen, hydrogen isotopes, and hydrogen carriers into thermal, mechanical, and electrical energies. The applications of these energies can be found in transportation (including aerospace), industrial, commercial, and residential sectors.
