Good day everyone,
I would like to model a humdififcation system on Simulink without need to use Simscape, I want the model also to control the level of Relative humidify for PEM Fuel Cell and return as well the power requirment of the humidifier.
I can't seem to find any online source or paper that showed how to model a humdification system on Simulink.

Thanks a lot @Jon. The first paper I know it but I failed in modelling on Matlab, the second website looks intresting, I am going through the Pdf. Do you have a built-in model already for a humdifier?
Thanks for the help

Sorry, no I don't have a humidifier model, I was just curious so I google searched to find the references I gave to you. In general, if you have a system of ode's (Ordinary Differential Equations) describing the evolution of the states of a dynamic system, you can build a Simulink model based upon the ODE's.
You probably are already familiar with this, but, the idea is that if I have a system of ODE's
dx1/dt = f(x1,x2,....)
dx2/dt = f(x1,x2,...)
etc
You then use an integrator block for each term, dx1/dt, dx2/dt, ...
The output of each integrator block is the corresponding xi, for example the output of the integrator block corresponding to dx2/dt would be x2
You then build up the inputs to each integrator block, using the output states from the integrator blocks, along with any additional external inputs.
So if a paper provides a model for a non-linear system, whether it is a humidifier or anything else, in the form of a set of ode's, it is pretty straightforward to make a Simulink model and simulate it.
