Performance analysis of Pem Electrolyser for green hydrogen production

With the global push toward decarbonization and sustainable energy solutions, the demand for clean hydrogen production using electrolysis has surged in recent years. The objective of this experimental study is to investigate the effect of applied voltage on the performance of Proton Exchange Membrane (PEM) electrolyser at different operating temperatures. The experimental tests are conducted using PEM electrolyzer equipped with a Nafion 115 membrane electrode assembly. The PEM electrolyser begins producing measurable hydrogen and oxygen only above a threshold voltage of 1.6 V. The highest hydrogen production observed was 13.88 ml/min at 2.54 V and 1.7 A. The findings from this study have significant implications for optimizing the performance of PEM electrolysers in clean hydrogen production.
