Automated system for automatic data acquisition for PEM electrolyzer

Proton Exchange Membrane (PEM) electrolyzers are crucial components in hydrogen production systems, where they play a significant role in splitting water into hydrogen and oxygen. However, the performance and longevity of PEM electrolyzer are highly dependent on the condition and integrity of the individual stacks within the system. Regular monitoring and maintenance of these stacks are essential to ensure efficient operation and prevent system failures. Traditionally, this process is labor dependent, requires human inspection and impedance measurement of each stack, which is time-consuming, prone to human error, and may lead to delayed detection of anomalies. Thus, developing an automatic system that constantly acquires data from the cell stack with the integration of sensors (such as current and voltage) can significantly improve cell efficiency, economize cost as cells are made of materials such as platinum which is highly expensive, also preventing changes in torque set and significant time conservation. The main objective is to apply this automatic system to multi cell stack arrangement, where only the total cell voltage and current can be acquired through software but not individual cell’s values. This research introduces an automated system to address the challenges encountered in multi-cell stack configuration.
