In this paper, we present a cost-effective system for monitoring and controlling alkaline electrolyzers, intending to improve hydrogen gas production on a laboratory scale. Our work includes two main innovations. Firstly, we suggest an approach to calibrate a standard air flow meter to accurately measure the flow of hydrogen-rich gas from electrolyzers, improving measurement accuracy while keeping costs low. Secondly, we introduce a unique cascade control method to manage hydrogen-rich gas production in the electrolyzer, ensuring precise control over gas flow rates. By combining affordable, energy-efficient devices with a PI control system, we achieve efficient gas production through electrolysis, replacing manual control approaches. Experimental results confirm the effectiveness of our cascade control method, demonstrating stable operation with minimal errors. These results provide a foundation for further research into control strategies to enhance the performance of electrolytic cells.
在本文中，我们提出了一种用于监测和控制碱性电解槽的经济高效系统，旨在提高实验室规模的氢气产量。我们的工作包括两项主要创新。首先，我们提出了一种校准标准空气流量计的方法，以准确测量来自电解槽的富氢气体流量，在保持低成本的同时提高测量精度。其次，我们引入了一种独特的级联控制方法来管理电解槽中的富氢气体生产，确保对气体流速进行精确控制。通过将经济实惠、节能的设备与PI控制系统相结合，我们通过电解实现了高效的气体生产，取代了手动控制方法。实验结果证实了我们的级联控制方法的有效性，表明其运行稳定且误差极小。这些结果为进一步研究提高电解槽性能的控制策略奠定了基础。
