How to set stoichiometric coefficient of proton and hydroxyl radical?

I used COMSOL 5.5 to model the electrochemical reduction of CO2. In my simulation, I choosed Electroneutrality, water based charge conservation option in Tertiary Current Distribution, Nernst-Planck (tcd) interface. However, it seems that I can not set stoichiometric coefficient of proton and hydroxyl radical when I try to describe electrode reaction as follows： H2O→1/2O2+2H(+)+2e(-) CO2+H2O+e(-)→CO+2OH(-) The interface of stoichiometric coefficient only includes the ions in Dependent Variables I added before. How can I set stoichiometric coefficient of proton and hydroxyl radical of electrode reactions under Electroneutrality, water based charge conservation option? Thanks.
