Thank you for the information.

1. the velocity looks wrong if it's zero at the inlet. Anyway, the flame speed of stoichiometric h2-air is about 2.4 m/s. This means that the flame will move upstream. So, it's not possible to get a flame shape looking like that in the paper. A quick calc (with some assumptions) shows that Re = rho*U*L/mu = 1.2*1*0.002/2e-5 = 120. So the flow is probably laminar.
2. the EDC model in general will require some kind of "ignition" (either patching or starting from a solution already having a flame). Did you check the temperature field after the initialization? 
3. The residuals plot does not have a key.
4. The mass balance is good but the heat fluxes look very unbalanced.
5. Did you check if the parameter values for the Sutherland viscosity actually make sense?
