How to solve x, y, and z on Matlab or excel?
I have tried many times but all times get negative values for x and y (using equation 7-13). If you have any idea or MATLAB code to solve these equations, then please let me know.
fuel composition is CH4=97%; CO2=1.5%; N2=1.5%
Air Composition is O2 =32%; N2=79%.
Please see this code
Code Solid oxide fuel cell code in the EES software

You can also use the Lagrange method. Please see attached Reference. Chapter 14. In recent works, we used the Lagrange method to model types of fuel cells.
Dear Abhinav, try to represent the equation as a function of 2 variables. The solution of this equation by the approximation method in Excel. It will allow you to obtain the desired dependencies.
