Electrolyte Phase Theory
The Electrolyte Phase node solves for the electric potential ϕl (V) as dependent variable.
The current density in the phase, il (A/m2), is defined as (Ref. 1)
(3-5)
where σl, eff is the effective electrolyte conductivity (S/m).
The charge balance equation in the phase is defined as
(3-6)
where iv,tot (A/m3) is the sum of a volumetric current density contributions of the electrode reactions occurring in the Gas Diffusion Electrode domains.
