Current collection on tubular fuel cell (SOFC)

I have a 2D model of a tubular solid oxide fuel cell and this is a working model although I didn't include current collection points. I had set up the electrochemical model using the Secondary Current Distribution physics and set an electric potential boundary condition at the cathode and an electric ground boundary condition at the anode. This in practice would not be possible, there would have to be a current collection point on the anode and one at the cathode, this would be for example metal contacts on both of the electrodes.
My question is how would I model this? Would I some how incorporate the metal contacts into the Secondary Current Distribution physics? Or would I add the Electric Current physics to model the current collection from the electrodes to the metal contacts and then apply the electric ground boundary condition at the anode current collector and electric potential boundary condition at the cathode current collector? I have added the model .mph file (I've removed the results as it made the file size too large) and a sketch of where I would like the current collectors to be.
Any help would be greatly appreciated. Thank you.
