MATHEMATICAL MODELLING AND OPTIMIZATION OF ELECTRICITY GENERATION IN MICROBIAL FUEL CELL BY USING SEWAGE SLUDGE

In Malaysia, renewable energy resources contributed to only 0.3% in electricity generation mix which was lower than other sources such as natural gas, coal, hydro, oil, diesel, and others. Solar, biogas, and biomass were the three sources of renewable energy that had a high potential to be utilized...
