Electricity and catholyte production from ceramic MFCS treating urine
Electricity and catholyte production from ceramic MFCS treating urine
Microbial fuel cells (MFCs) offer a promising technology for electricity production. In the anodic chamber, an anaerobic biofilm breaks down the organic compounds present in the urine to generate electricity. In the cathodic chamber, the oxygen reduction reaction (ORR) contributes to the catholyte generation, together with the electroosmotic drag and the diffusion through the ceramic membrane. This work evaluates the effect of the thickness of a ceramic membrane, in the power generation, as well as for the first time study the catholyte produced from the MFCs using urine as a feedstock. Cylindrical MFCs were assembled with fine fire clay of different thicknesses (2.5, 5 and 10 mm). The power and the amount of catholyte decreased with the wall thickness, whereas the pH of the catholyte increased. The possibility to produce different quality of catholyte from urine opens a new field of study in water reuse for practical implementations.

Abstract
Microbial fuel cells (MFCs) offer a promising technology for electricity production. In the anodic chamber, an anaerobic biofilm breaks down the organic compounds present in the urine to generate electricity. In the cathodic chamber, the oxygen reduction reaction (ORR) contributes to the catholyte generation, together with the electroosmotic drag and the diffusion through the ceramic membrane. This work evaluates the effect of the thickness of a ceramic membrane, in the power generation, as well as for the first time study the catholyte produced from the MFCs using urine as a feedstock. Cylindrical MFCs were assembled with fine fire clay of different thicknesses (2.5, 5 and 10 mm). The power and the amount of catholyte decreased with the wall thickness, whereas the pH of the catholyte increased. The possibility to produce different quality of catholyte from urine opens a new field of study in water reuse for practical implementations.
