PEM Electrolyzer Model: Fundamentals and Theoretical Concepts

Understanding the losses inside the cell before dropping an electrolyser into a process simulator as a black box is the right order. According to the video description and chapter titles, the lesson moves through the cell model, mass transfer, thermodynamics and overpotentials. Cell voltage is the reversible voltage plus activation, ohmic and concentration losses. At 25 °C and 1 bar the reversible cell voltage for water splitting is about 1.23 V; the thermoneutral voltage is about 1.48 V. Simulation results should not be used as design data until model parameters are calibrated against a real polarisation curve. The content part of the description is short and relies mostly on section titles; the presenter is not named and the channel also points to paid courses.
