Hello and hope you are doing well.

I have to model the alkaline electrolyzer in EES to continue the simulation of my thermal power plant cycle. The electrolyzer is the start point of mine. I've read a couple of articles, especially Ulleberg's. I need to develop a model to specify the temperature and pressure of the oxygen and hydrogen to achieve the thermodynamic properties.

In the mentioned article (Ulleberg), I've seen some parameters that are not clear to me. Also, I need to know the flowchart of the solution (which parameters should be considered as assumptions and which ones should be calculated numerically in EES).

Here is the link to the mentioned article:

I'd thank you if you give me a couple of hints to start the modeling.

I appreciate your help in advance.
