The electrochemical model of the vanadium redox battery is compared in this section to
experimental data. To determine the performance, a VRB composed of a 19 elements stack and
two tanks filled with 83 l of electrolytes will be used. The total vanadium concentration in each
electrolyte is 2 M. The characteristics of the stack are summarized in Tab. 3 and correspond
to an experimental stack built by M. Skyllas-Kazacos and co-workers (Skyllas-Kazacos &
Menictas, 1997). The electrochemical model is used to assess the stack efficiencies during a
series of charge and discharge cycles at constant currents
