Abstract

This study investigates the composition of metal ions using micronutrients to improve energy generated through MFC. Metal ions as micronutrients were investigated, utilizing various metal ions: pumblum, calcium, cobalt, cadmium, chromium, and zinc at various concentrations. Food waste was used to sustain mimicrooragnisms, which were converted into electrons. Metal ions promote bacterial metabolism through the transformation and distribution electrons. The study found that cobalt at 3 μg/L produced the highest voltage, current density, and power density of 4.5 V; 522 mA/m²; and 1,085 mW/m², respectively. Our findings from studies reveal that cobalt succeeds in enhancing electricity.
