Fabrication of the macro and micro-scale microbial fuel cells to monitor oxalate biodegradation in human urine

Abstract This study presented the fabrication of macro and micro-scale microbial fuel cells (MFCs) to generate bioelectricity from oxalate solution and monitor the biodegradation in a micro-scale MFC for the first time. The maximum generated power density of 44.16 W m−3 in the micro-scale MFC elucid...
