This study aims to develop a model of alkaline electrolysis to compare the performances of AEM and conventional electrolysis cells under various operating conditions, including changes in electrolyte composition for hydrogen production. The results show that over-potential behaves differently depending on the type of electrolyzer and electrolyte used. This electrolytic cell model will serve as a benchmark for further development of a comprehensive representation for alkaline electrolysis, which can be utilized for simulation and developing controlled algorithms for hydrogen production.
This work is an attempt to develop a model of alkaline electrolysis to compare AEM and conventional electrolysis cells performances over several operating conditions, including a change in electrolytes' composition for hydrogen production. It shows that over-potential behaves differently with whether an AEM/conventional electrolyser is used, or NaOH/KOH electrolyte is used. This model of the electrolytic cell will be a benchmark for developing a further complete representation for alkaline electrolysis which can be used for simulation as well for developing control algorithms-controlled hydrogen production.
