i have some questions about the PEM fuel cell.
1) how can i change the porosity, density, temperature and velocity (profile velocity along the x-axis) and if i changed them what is effect and the results that i will get ?
2) about the chemical equation why it is only valid for 25 C ?
3) what are the equations that is used in the model of the species transport in the GDL's of a PEM ? and why did we use these equations ?
4) why do we use the mesh ? and why did we use the tetra mesh in this model ? how many type of mesh do we have ? and what is mesh sensitivity ?
5) how can i put dimensions on the model ?
please answer these questions if you can :D , thanks in advance.
best regards.
