Explicitly, it accounts for substrate inhibition, enzyme concentration, mediator dynamics, and electrochemical reactions to determine optimal working conditions. In the MET model, the Nernst Ping-pong model is used to account for mediator-dependent electron transfer and overpotential effects. Simulation results show that the DET current peaks at 1.2 mol m⁻³ substrate with 1.05 mA, whereas the MET current peaks at 1.25 mA for a lower concentration of 0.94 mol m⁻³. Furthermore, a 50% and 45% degradation of the catalytic current is observed at a 5 mol m⁻³ substrate concentration for both. The model identifies an optimal mediator concentration of 77 mM and shows that increasing mediator loading from 50 to 100 mM enhances the catalytic current by ~ 30–35%, whereas increasing the overpotential from 0.05 to 0.2 V results in a comparatively smaller improvement of ~ 10–15%. This indicates that EGFC performance is significantly more sensitive to mediator loading than to overpotential within the investigated range.
