Dynamic modelling of alkaline self-pressurized electrolyzers: a phenomenological-based semiphysical approach

"This paper proposes a phenomenological based semiphysical model (PBSM) for a self-pressurized alkaline electrolyzer. The model, based on mass and energy balances, represents the dynamic behaviour of hydrogen and oxygen production using electrolysis. The model allows to anticipate operational v...
