A kinetic model of the bio-anode was developed based on a simple representation of the underlying biochemical conversions as described by enzyme kinetics, and electron transfer reactions as described by the Butler–Volmer electron transfer kinetics. This Butler–Volmer–Monod model was well able to describe the measured bio-anode polarization curves. The Butler–Volmer–Monod model was compared to the Nernst–Monod model described the experimental data significantly better. The Butler–Volmer–Monod model has the Nernst–Monod model as its full electrochemically reversible limit. Contrary to the Nernst–Monod model, the Butler–Volmer–Monod model predicts zero current at equilibrium potential. Besides, the Butler–Volmer–Monod model predicts that the apparent Monod constant is dependent on anode potential, which was supported by experimental results.
