An Algebraic Model for a Zinc/Bromine Flow Cell

An algebraic model for a parallel plate, zinc/bromine flow cell is presented and used to predict various performance quantities, which are compared to those predicted by using previously published differential equation models. The results presented compare well with previous work. The model is based on the concept of using well‐mixed zones and linear concentration and potential profiles for the diffusion layers and the separator. The Butler‐Volmer equation is used for the electrochemical reactions, and the homogeneous reaction between bromine and bromide is included.
