Scaling up self-stratifying supercapacitive microbial fuel cell (2020)
Journal Article
Walter, X. A., Santoro, C., Greenman, J., & Ieropoulos, I. A. (2020). Scaling up self-stratifying supercapacitive microbial fuel cell. International Journal of Hydrogen Energy, 45(46), 25240-25248. https://doi.org/10.1016/j.ijhydene.2020.06.070

Self-stratifying microbial fuel cells with three different electrodes sizes and volumes were operated in supercapacitive mode. As the electrodes size increased, the equivalent series resistance decreased, and the overall power was enhanced (small: ES...

The microbial fuel cell (MFC) technology relies on energy storage and harvesting circuitry to deliver stable power outputs. This increases costs, and for wider deployment into society, these should be kept minimal. The present study reports how a MFC...

In recent years, human urine has been successfully used as an electrolyte and organic substrate in bioelectrochemical systems (BESs) mainly due of its unique properties. Urine contains organic compounds that can be utilised as a fuel for energy recov... Read More about Urine in bioelectrochemical systems: An overall review.

Scalability and stacking of self-stratifying microbial fuel cells treating urine (2020)
Journal Article
