I have studied about PEMFC simulation with out using module.

I simulate in steady state and solution converge but I think, my solution has some problem about species diffusion.

My anode inlet boundary condition is pressure inlet and set gauge pressure equal to 202650 Pa.

My cathode inlet boundary condition is velocity inlet and set velocity equal to 0.104 m/s.

Fluid look like does not flow to outlet and diffuse to GDL and catalyst layer.

I attach my contour of hydrogen and oxygen.

Please answer me, what problem in my simulation?

Thank you very much.
