Mass constraint Question

I'm modelling a Electrochemical cell, where I have the formation of Chlorine on one electrode and the formation of hydrogen on the other electrode. Initially Sodium Chloride is dissolved in water, where Chloride ions is then oxidized at the anode and Water is oxidized at the Cathode.
All species in liquid form is handled using Transport of Dilute Species since there is abundance of water compared to the other species in the liquid phase.
The species in gaseous phase is handled using Transport of Concentrated Species, but here is my problem.
In this module I have to select one species for Mass Constraint but this means that I cannot specify that this species should just be formed at one of the electrodes and not be present in the entire domain.
Does anyone know how I let COMSOL that the species from the Mass Constraint is limited to a certain boundary?
I have attached my model, so you guys can see the problem. In this case the problem is the formation of Chlorine and not Hydrogen.
Best Regards,
Nikolaj.
