These studies carried out to know the effect of ammonium on the current generation in the microbial fuel cells (MFCs). MFCs used in the study were enriched with anaerobic digestion sludge and operated for 3 years using artificial wastewater (AWW). When the current was stably generated, ammonium ion with $27.0{\pm}0.0$, $51.5{\pm}0.0$, $103.5{\pm}0.0mg/L$ with acetate fed into the anode compartment. The current values under condition included ammonium were changed from its initial $6.30{\pm}0.06$ to $6.28{\pm}0.36$, $5.95{\pm}0.61$, $5.64{\pm}0.38mA$, respectively. The current value was slightly decreased to $5.64{\pm}0.38mA$ compared to $6.30{\pm}0.06mA$ generated from MFC without ammonium ion in the AWW. But After 3days operating under ammonium concentration with $103.5{\pm}0.0mg/L$, the current was unstably generated when artificial wastewater without ammonium was fed again. MFC enriched with AWW without ammonium ion was inhibited by high concentration of ammonium. At this time, the ammonium was removed 5.27~16.41 mg per day under all conditions.
