Aspen Plus: Calculation of the current voltage polarization curve of a PEM electrolysis stack

PEMEL (polymer electrolyte membrane electrolysis) enables hydrogen production from pure water.

It is well developed and commercially available up to megawatt for industrial applications.

In a PEMEL cell, water is introduced at the anode where it is split into protons, oxygen and electrons. The protons and the electrons travel through a membrane and an external circuit to the cathode to form 𝐻_2, while oxygen remains back with water.

In this video, the current-voltage polarization curve of a PEM electrolysis stack will be generated using ASPEN PLUS
