binary diffusion in steady state

i have trouble in my simulation.
i'm trying to confirm whether diffusion is really working in Fluent.
so, i set some conditions like below.
model : VOF ✔implicit-body-force
species-Transport ✔diffusion-enertgy~ ✔full-multicomp~
phase : primary-phase = mixture-template
secondary-phase = hydrogen
cell-zone-conditions : no change
boundary-conditions : no change(no inlet, no outlet)
solution-methods : PISO
we made patch at solution-initialization in half of the material.
so i could get the state that there were hydrogen phase and mixture-template phase in the material.(see figure)
and then, i trid to run-calculation. the calculation ran, but there was no change between two phasese. it was same at time 0.
so i have not confirmed binary diffusion.
please teach me how to confirm binary diffusion.
