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
The method published in the Paper

Can you upload a video of the whole simulation process described in the paper?

Great work !!

Thanks🙂

Thank you so much for your video ;D

[@kgengineeringsolutions]

You're welcome

I have a question. When you write the equation "Actual current density (i_A)" 30:53, isn't it i_A = i*nF istead of i_A = i/nF?

[@kgengineeringsolutions]

@@GJ-iy5kj The Faraday efficiency relates the theoretical electrical current needed to carry out the electrolysis reaction with the real intensity circulating through the cell: F=theoretical electrical current/actual electrical current

Waiting this video from long time Thank youu

You're welcome. More videos about electrolysis will be uploaded this year🙂

Thank you so much for the youtube video! Would you be able to carry out the entire PEM Electrolysis Stack Modelling on Aspen Plus showing us how to achieve the same output of hydrogen gas as described in the paper: "Experimental and theoretical evaluation of a 60 kW PEM electrolysis system for flexible dynamic operation"? I would really appreciate if you could model the PEM water electrolysis stack to work with the intermittent and dynamic energy supply from wind turbines. Would you be keen on working on these in the near future?

[@kgengineeringsolutions]

You're welcome. I don't know if one can simulate a process like this with Aspen Plus, so I can't promise you anything.

Thanks for your share. 4.08 1:22 s i click excel and i get "unable to create Excel file from Template" error. Do you mind how can i fix it?

Do you have the simulation of aspen plus for PEM hydrogen from seawater?

[@kgengineeringsolutions]

unfortunately no

Can you tell me where the “add-ins” in your example come from ， why I don't have them on my computer?Thank you

I mean how do you plug in the aspen temperature value that I can't find in my Excel
