hi,
i'm pretty much new to working with simulations.
i want to simulate just the bipolar plate + gdl layer in a pemfc. this way, i think it wouldn't be necessary to take into account the water saturation and electrochemical analysis, for example.

could you help me choose how to properly model a single channel? which solution models take into account?

i'm starting with just the basics:
constant velocity at the channel inlet
constant pressure at the channel outlet
no-slip condition at the walls
defining the GDL porosity
02 for the cathode flow
