Abstract
Microbial fuel cell is an alternative technology for energy generation aiming to recover chemical energy from biodegradable wastewater to and convert it to electricity.
In this study, a small laboratory-scale microbial fuel cell was evaluated to generate electricity using cheese whey wastewater as the sole nutrient source. The open-circuit potential and the stable voltage output with 1000 Ω external resistance of the fuel cell using only cheese whey wastewater as anolyte were 0.925 V and 0.379 V, respectively. The power density achieved by the cell was 7.18 mW m–2, with a maximum current density of 35.75 mA m–2. The series connection of seven fuel cells produced the open-circuit potential of 7 V that could run a 4 V LED light strip for more than 3 hours. Cheese whey-microbial fuel cell can be considered as a cost-effective renewable energy source for the operation of low energy demanding devices in the future.
