The transition to renewable energy sources requires efficient energy storage and conversion systems. Among these, AEM (Anion Exchange Membrane) electrolyzers have emerged as a promising technology for green hydrogen production due to their potential to combine the advantages of both alkaline and PEM electrolyzers. However, their long-term performance and degradation behaviour under real operating conditions remain crucial aspects for industrial-scale deployment. This thesis project, developed in collaboration with Edison S.p.A., presents the modelling of a realistic AEM electrolyzer test bench. In particular, the aim of this Python-based simulation model is to simulate the dynamic behaviour of AEM electrolyzers, integrating both their electrical response and degradation over time.
